The Most Exciting Football Jerseys Released This September 2026

September might be the start of a new football season, but it is also becoming one of the most interesting months of the year for football shirt releases. As the 2026/27 campaign gets into full swing, clubs and national teams are unveiling special editions, retro-inspired designs and completely new ideas that give fans even more reasons to update their collections.

From Inter Milan's 1990s-inspired third kit to Bayern Munich's colourful Oktoberfest shirt and Manchester City's fan-created AI jersey, September 2026 has already delivered some seriously memorable designs.

Here are some of the most exciting football jerseys released this September 2026.

1. Inter Milan 2026/27 Third Jersey

Inter Milan and Nike unveiled their new 2026/27 third kit on September 14, and the design immediately caught the attention of football-shirt fans. The jersey takes inspiration from Inter's distinctive 1990s aesthetic, with the club describing the concept through its broader Milan identity and fashion culture.

The shirt features a darker base with bold blue detailing and a prominent horizontal design, creating a look that feels both nostalgic and modern. The biggest attraction is the connection to Inter's famous 1997/98 third shirt, an era strongly associated with the club's iconic Ronaldo years.

This is exactly the kind of design that explains why retro football jerseys continue to have such a strong influence on modern football fashion. Instead of simply reproducing an old shirt, Nike has taken familiar references and rebuilt them for a new generation.

For collectors, the Inter third jersey is particularly interesting because it works as both a football shirt and a streetwear piece.

2. FC Bayern Munich 2026 Wiesn Jersey

Bayern Munich's latest Wiesn jersey was officially released on September 14, bringing one of the club's most recognisable traditions into a completely new design. Created with adidas for Oktoberfest season, the shirt combines Munich tradition with a much more colourful and contemporary visual identity.

The standout feature is its bold multicoloured floral pattern, which Bayern says represents the lively, diverse and vibrant atmosphere of the Wiesn. The shirt also includes the specially designed FC Bayern Wiesn emblem, the adidas Originals trefoil and an Oktoberfest logo detail on the back of the neck.

It is a major departure from more conservative Bayern designs, and that is precisely what makes it interesting.

The jersey will be worn by Bayern for the first time in their home game against Union Berlin on September 18, 2026, while the shirt is already available as part of the club's Oktoberfest collection.

The new Wiesn shirt also proves that special-edition football jerseys don't have to follow traditional football design rules. Culture, fashion and local identity can be just as important as the club colours.

3. Chelsea 2026/27 Third Jersey

Chelsea unveiled their new 2026/27 third kit on September 12, completing their trio of Nike releases for the season. The new shirt takes a distinctly retro approach, inspired by Chelsea away and third shirts from the 1980s and 1990s.

The design is predominantly white, with blue trim and vertical red pinstripes. One of the most noticeable details is the use of a retro Chelsea crest, giving the shirt an immediate vintage character.

The men's version also features white shorts, while the overall kit is completed with white socks featuring blue hoops. Chelsea's campaign presents the shirt around the idea of being different and standing apart, which fits perfectly with its bold throwback appearance.

For football-shirt fans, this is another example of the 2026/27 season leaning heavily into nostalgia.

Instead of looking futuristic, some of the most interesting new football jerseys are looking backwards — taking inspiration from the designs that made football fashion so distinctive in previous decades.

4. Croatia's New adidas 2026 Kits

September also brought a major change for international football jerseys, with Croatia unveiling its first kits with adidas as part of the new partnership between the brand and the Croatian Football Federation. The new home and away shirts were revealed in September, giving the famous Croatian identity a fresh interpretation.

The home jersey retains Croatia's iconic red-and-white checkered identity but incorporates subtle references to Glagolitic script, one of the historic writing systems associated with Croatian culture. The away design moves into a dark navy palette and draws inspiration from Croatian lace-making traditions.

This is an excellent example of how national-team jerseys can communicate more than football.

The best international shirts often tell a cultural story through colours, patterns and symbols, and Croatia's latest collection does exactly that. It gives the classic checkerboard a new visual language without abandoning the country's instantly recognisable identity.

For fans searching for distinctive football jerseys 2026, the Croatia collection is one of the more culturally detailed releases of the month.

5. Manchester City's Fan-Designed AI Third Kit

Manchester City's new 2026/27 third kit may be the most unusual release of the month because of how it was created.

PUMA and Manchester City gave supporters the opportunity to design the club's next third shirt using the PUMA AI Creator platform. More than 180,000 unique shirt concepts were created, and the winning design was eventually selected through fan voting.

The final jersey has a white base with a central two-tone sash, split between sky blue and navy, with a subtle gradient effect. It is a relatively clean design, but the story behind it makes it completely different from a conventional football-kit launch.

This could be one of the biggest developments in football shirt culture: supporters are no longer just buying the finished product; they are beginning to participate in the design process itself.

Manchester City describes the jersey as professional football's first fan-designed AI kit to be worn on the pitch and sold to supporters.

That makes this shirt much more than another 2026/27 third kit. It represents a new intersection between football, fashion, technology and fan culture.

Why September 2026 Is Such an Interesting Month for Football Jerseys

Looking at the biggest releases from September, one trend immediately stands out: football shirts are becoming increasingly creative.

Inter is looking back to the 1990s.

Chelsea is bringing vintage details into a modern Nike design.

Bayern is connecting football with Oktoberfest culture.

Croatia is using national history and traditional craftsmanship as design inspiration.

Manchester City is using artificial intelligence and fan participation to create something completely new.

These approaches are completely different, but they all show that a football shirt can be much more than a team's colours.

The Rise of Football Jerseys as Fashion

That evolution is especially important because football jerseys are now being worn far beyond stadiums.

Retro kits, third shirts and special-edition designs have become popular with people who may not even support the club on the shirt. The colours, graphics, historical references and oversized silhouettes can work just as well with jeans, trainers, shorts and other streetwear pieces.

This makes the 2026/27 football kit season particularly exciting for anyone interested in football fashion.

A shirt can now be a piece of sporting history, a collector's item, a fashion statement or simply a great-looking part of an everyday outfit.

What Makes a Football Jersey Stand Out?

There is no single formula for creating a memorable football shirt.

Sometimes it is nostalgia. Inter and Chelsea show how powerful a 1990s-inspired design can be.

Sometimes it is culture. Bayern and Croatia demonstrate how local traditions can be incorporated into football fashion.

Sometimes it is innovation. Manchester City's AI-generated jersey suggests that technology could play a much bigger role in how future kits are designed.

And sometimes the simplest thing works best: a strong colour combination, a memorable badge or a design that immediately feels different.

That is why collecting football jerseys has become so popular. Every season offers something new to discover.

More Exciting Football Jerseys Are Still Coming

September 2026 is clearly not finished with football shirts yet. With clubs still revealing special editions, third kits and alternative designs, the final months of the year could bring even more standout releases.

For fans, that means more opportunities to find unusual shirts, discover new football fashion trends and add something different to their collection.

Whether you prefer retro football jerseys, modern third kits, international shirts or special-edition designs, the 2026/27 season has already given collectors plenty to talk about.
