The eye-catching tuxedo kit of Spanish lower-league team Cultural Leonesa was worn by players in a preseason tournament.
The third division club commissioned the jersey as a tongue-in-cheek way of celebrating its 90th anniversary.
A percentage of the profits from sales of the special edition kit will go to local charities.
Despite the worldwide attention garnered by the unique design, Cultural Leonesa will not wear the anniversary kit in the new season, which begins in mid-August.
Other Spanish clubs have also designed creative preseason strips in recent times. This Deportivo Lugo kit is based on a pint of beer, a specialty of the Galicia region where the club is based and reflecting its sponsor.
Another culinary trademark of Galicia is Pulpo Gallego, the local octopus dish, which is why this Deportivo Lugo kit is embossed with a giant red tentacle.
You have to look extremely closely (with a magnifying glass), but this kit worn by Deportivo Alaves contained the name of every season ticket-holder at the club in the 2000-01 La Liga season.
This Barcelona away kit from last season is essentially a wearable version of the Catalan flag, affirming the club's strong regional identity.
Athletic Bilbao's 2011-12 away strip was also a statement of regional pride, incorporating the colors of the Basque flag.
This slightly more obvious commercial venture by Atletico Madrid aimed to promote the "Spiderman 2" movie upon its release in 2004.
Another kit rich in local significance is the heart-patterned, blue and white jersey of Dutch side Hereenveen. Hearts also adorn the flag of Friesland province, where the town of Heerenveen is located.
What's in a color? Quite a lot if you're a fan of Cardiff City. The Welsh club's Malaysian owner Vincent Tan changed the traditional blue jersey to red in 2012 as he wanted to make the team more popular with Asian supporters. Needless to say, this was to the frustration of much of Cardiff's local support.
Former Mexico goalkeeper Jorge Campos used to design his own uniforms. This particularly bright number worn at the 1994 World Cup was said to be inspired by his country's Aztec history.
