A football shirt and a football kit are not exactly the same thing. The shirt is the garment you wear. The kit is the full system – a regulated set of colours, numbers, badges, and design rules approved by organisations like FIFA, UEFA, and domestic leagues.
On the surface, soccer kits look simple: a shirt, shorts, and socks in club colours. But behind every season’s design is a framework of competition rules, commercial deals, and technical requirements.
So how do soccer kits work, and why do clubs release new ones every year? Let’s take a closer look.
Player Cut vs Fan Cut: The Two Versions of Every Soccer Kit
Every major club and national team kit comes in at least two versions. One version is built for playing, the other for wearing in the stands or everyday life. The player version is not simply a more expensive replica, it is a functionally different garment.
HOME KIT
Primary identity
Required at home unless clash
Nike terminology: Match or Dri-FIT ADV (player-tier). Adidas: Authentic. Puma: Player Edition.
Player-cut fit: slim, sits close to the body. VaporKnit and equivalent technical fabrics are designed to move with the player and manage heat.
The hem shape on authentic versions may differ from the fan version for freedom of movement under shorts.
Generally, costs significantly more than the replica equivalent. Some player-specification shirts are only available direct from clubs rather than general retail.
AWAY KIT
Colour-clash resolution
Required when colours conflict
Nike terminology: Stadium or Dri-FIT (fan-tier). Adidas: Replica. Puma: Fan Edition.
Standard fit: more relaxed through the chest, shoulders, and sleeves. Less structured around the body than the player version.
Uses standard performance polyester rather than the top-tier technical fabrics. Still moisture-managing, but the specification is closer to general activewear than match wear.
This is the most common version found in general retail. Most officially licensed jerseys sold through club shops and licensed retailers are stadium/replica tier.
THIRD KIT
Additional alternative
Used when home + away both clash
Third kits are usually released in the same player/fan two-tier structure as home and away.
Third kits exist because UEFA and domestic competition rules require that all three kits be visually distinct from each other and from opponents’ kits.
Clubs have more creative latitude with third kits. These designs are sometimes the most commercially adventurous of the three – unusual colours, fashion collaborations, or anniversary references.
Third kits are not used every season in competition. Many fans buy them as a standalone design piece rather than for match attendance.
For everyday wear: fan-cut (stadium/replica). For the closest match to the on-pitch garment: player-cut (authentic/match). A small number of player-tier shirts are team-issued only and not available at retail.
QUICK TIP
Player-cut shirts in football run small by general clothing standards. The slim fit is designed for an athlete in peak condition. Most buyers find sizing up one, sometimes two, from their usual size gives a more comfortable everyday fit. Fan-cut shirts are usually consistent with standard clothing sizing.
Home, Away, Third: How Club Kit Systems Work Each Season
The three-kit system exists primarily because competition rules require a visual distinction between teams on the pitch. UEFA Equipment Regulations (2024) govern shirt structure, colours, and combinations for all UEFA competitions. Domestic leagues maintain parallel regulations.
The system works on a hierarchy: home kit by default, away kit when a colour clash exists, third kit when both home and away would conflict.
Commercially, the three-kit structure creates three purchase opportunities per season. Clubs release the home kit first, followed by away and third. Each kit is produced by the club’s manufacturer under a multi-year deal negotiated independently of league-wide arrangements.
DID YOU KNOW
UEFA Equipment Regulations specifically govern ‘shirt structure, colours and patterns’ and ‘colour choices and combinations’ for all UEFA-sanctioned competitions. Player lists submitted for UEFA competitions include shirt number and name ‘if applicable’ linking the visual identity of the kit directly to competition administration.
IFAB Law 4 (Equipment) establishes the baseline for all association football: compulsory equipment must include a shirt with sleeves, and shirt markings are generally limited to the player’s number, name, team crest or logo, and advertising permitted by competition rules.
Why the Messi PSG Jersey Became So Famous
Paris Saint-Germain signed Lionel Messi in August 2021. Neymar Jr. already held #10 at PSG, so the Messi PSG jersey carried #30, not his career number. In Ligue 1, squad allocations are not free-form: Gianluigi Donnarumma was granted special permission to wear #50 specifically because Messi had taken #30. The number and the administrative detail behind it became part of the immediate story around the PSG Messi jersey.
“PSG describes itself as a global brand at the intersection of sport, culture and fashion, a framing that predates the Messi signing and explains why those kits carried different cultural weight.”
— PSG official positioning, psg.fr
The second reason the Messi jersey attracted particular attention was structural: PSG had been in a commercial relationship with Jordan Brand since 2018. Nike supplies the match kits. Jordan Brand, as a Nike subsidiary, provided a parallel identity layer – the Jumpman logo appeared on select PSG shirts and limited releases.
The combination, an unexpected squad number and a Jordan Brand identity layer, meant the PSG Messi jersey editions from 2021-23 circulated across fashion and streetwear coverage well beyond standard football channels.
COLLECTOR NOTE
The PSG-Jordan collaboration has produced limited releases, including Air Jordan 1 designs bearing PSG branding. These sit at the intersection of football merchandise and sneaker culture, a category that has no equivalent at most other European clubs. The Messi-era PSG shirts specifically (2021-22 and 2022-23 seasons) are the two seasons in which the most-searched player in club football wore an unusual number in a Jordan-branded visual system.
World Cup Jerseys: From 1930 to Today
The World Cup kit system accumulated gradually from 1930, when no standardised numbering existed, to today’s framework of 26 registered squad numbers per team, pre-approved designs, and manufacturer restrictions.
Tournament | Number System | Notable Kit Moment | |
|---|---|---|---|
1930 Uruguay | None fixed | None | Squad numbering did not exist. Players were assigned numbers by starting position on the day of the match, or not at all. Brazil’s kit in this era was simple white with no consistent number system. |
1938 France | Positional 1–11 | None | The convention of numbering by position (1=goalkeeper, 2–11=outfield starting players) became standard. Squad numbers beyond 11 were not used for registered reserves. |
1958 Sweden | 1–22 (squad assigned) | Brazil No. 10 Pelé | Brazil failed to submit squad numbers in advance. FIFA assigned them alphabetically by player surname within the submitted squad. Pelé was listed under ‘E’ (Edson) and received No. 10. He wore it through the championship. The number, and what he did in it, connected the two permanently. |
1970 Mexico | Squad numbers | No. 9 Müller | First World Cup broadcast globally in colour. Shirt design and number visibility became part of the televised spectacle for the first time. Gerd Müller (West Germany) scored 10 goals in No. 9. |
1994 USA | Squad list registered | No. 10 Romário | FIFA began enforcing pre-tournament squad number registration more rigidly. Players kept their registered number for the duration of the tournament regardless of match circumstances. |
2002 Korea/Japan | 1–23 (squad size) | No. 10 Ronaldinho | Squad size standardised at 23 players. Numbers 1–23 registered per team; No. 1 reserved for the starting goalkeeper. The modern tournament numbering framework now in use was essentially in place by this point. |
2022 Qatar | 1–26 (expanded) | No. 10 multiple | FIFA expanded squad sizes to 26 players for this tournament (having temporarily used 26 at Euro 2020 and Copa América 2021 due to COVID). The 26-number registration range now covers the full squad for all FIFA tournaments at senior level. |
In 1958, Brazil did not submit squad numbers in advance. FIFA assigned them alphabetically. Edson Arantes do Nascimento, whose name filed under ‘E’, received #10. He was 17, scored six goals, including two in the final, and the number became inseparable from the global image of the No. 10 role.
World Cup kit approval is separate from domestic approval. Tournament specifications (seam placement, badge dimensions, fabric standards) are reviewed by FIFA independently, even when the visual design matches the club or national team’s regular shirt.
WORTH KNOWING
Replicas marketed as ‘World Cup match shirts’ can refer to several different tiers: official tournament player shirts, official national team shirts (sold outside the tournament window), and replica fan versions. The FIFA logo on a shirt does not in itself indicate tournament specification, it indicates licensed use of FIFA’s intellectual property for that national federation’s kit. Tournament-specification shirts are the least commonly available tier and are not typically sold through standard retail.
Premier League, La Liga, Serie A: How Kit Deals Differ by League
Individual clubs negotiate their own manufacturer deals in every major league. What differs is how much each league centralises the visual presentation of names, numbers, and badges.
PREMIER LEAGUE
England · 20 clubs
In 2023/24 the league announced updated specifications for names and numbers across all 20 clubs: font, sizing, and colour treatment follow a league-level template rather than a club-level choice. Sleeve badges are also subject to Premier League specification.
LIGUE 1
France · 18 clubs
The rules specify that the printed name must exactly match the official squad list – no nicknames, no initials, no non-Latin characters without formal exception. The Mbappé jersey during his PSG years and Kai Havertz jersey at Arsenal both fall within their respective leagues’ name presentation rules – Ligue 1 and the Premier League apply different but equally strict templates. The Messi #30 / Donnarumma #50 situation is cited in Ligue 1’s own documentation as an example of how squad number allocation works.
SERIE A
Italy · 20 clubs
The 2024/25 season brought specific changes including new constraints on metallic number colours.
LA LIGA
Spain · 20 clubs
Real Madrid (white), Barcelona (blue and garnet), Atlético (red and white) are all associated with long-established colour identities. LaLiga produces fewer league-wide standardisation decisions than the Premier League. Away kits are entirely club-led.
Soccer Jersey Fit Guide for Fans
Football shirts assume no equipment beneath them. Player-cut versions are among the most fitted performance garments in team sports. Even replica versions sit narrower in the shoulder and shorter in the hem than NHL or NFL jerseys at equivalent labelled size.
Soccer Shirt | NBA Jersey | NHL Jersey | MLB Jersey | |
|---|---|---|---|---|
Designed for | Player on pitch (no padding) | Player on court (no padding) | Player over pads (shoulder/chest) | Batter/pitcher (no pads) |
Player-tier fit | Slim/tailored. VaporKnit or equivalent tech fabric | Close athletic fit. Dri-FIT mesh panels | Tailored — but still sized for pads | Relaxed-athletic. Cool Base / Flex Base |
Fan-tier fit | Standard fit. Replica/Stadium cut | Fan Swingman: relaxed | Loose. Game jersey | Fan replica: relaxed |
Typical fan shirt L chest (approx.) | ~40–42″ chest | ~41–44″ chest | ~41–43″ chest (assume pads add 4-6″) | ~41–44″ chest |
Length at size L | Shorter hem. Ends near hip | Short/mid hem. Athletic crop length | Longer hem. Covers thigh | Longer hem. Covers hip/thigh |
Buy for streetwear? | Fan cut = relaxed, suitable. Authentic = tight, size up | Fan cut = comfortable for everyday | Size down significantly if no pads | True to size |
Collar style | Crew or V-neck, typically crewneck | Sleeveless / tank cut | V-neck or crew with fight strap | Button-front or full-button opening |
The safest approach when crossing sports: check the brand’s chest measurement chart. The same size label produces different garments depending on whether the jersey was designed for pads, an athletic body, or a slim football cut.
OUR TIP
Football shirt sizing varies slightly between European brands. Adidas football shirts generally run slightly larger in the body than Nike at equivalent sizes. Puma football shirts tend to run true to size for fan versions. If ordering internationally, confirm whether the sizing chart uses UK/EU sizing (S/M/L/XL) or US sizing, as some clubs use one and some the other within the same season.
Soccer Kit FAQs
Competition rules require kits to meet current technical and visual standards, which change over time. Clubs also release new kits annually for commercial reasons, since new designs generate licensing revenue for clubs and manufacturers. Historically, kits often lasted several seasons, with many clubs keeping the same look for five to ten years. The shift to yearly releases accelerated in the 1990s as television coverage and the global kit market expanded.
Not freely. Squads submit a registered number list before the tournament. No. 1 is reserved for the starting goalkeeper. The rest are distributed among the 26-player squad. The 1958 Brazil example, where Pelé received #10 through alphabetical assignment, was a consequence of the looser registration process of that era.
PSG has collaborated with Jordan Brand since 2018. Select kits carry the Jumpman alongside the Nike Swoosh. The arrangement is specific to PSG, no other major European club has replicated the same co-branding structure at kit level.
An official licensed replica is produced by the official kit manufacturer under licence from the club or national federation. It copies the visual design of the match shirt but uses fan-tier construction – standard polyester, relaxed fit, and simpler customisation. “Official licensed” distinguishes the shirt from counterfeit or unofficial merchandise, but it does not mean it is player-spec.
Yes. Under UEFA Equipment Regulations and domestic league rules, all kits used in competition (home, away, and third) must meet the same standards for structure, colour contrast, name and number presentation, and badge placement. Clubs must ensure every kit worn in official matches provides clear visual distinction from the opponent.
