Football shirts were once a symbol of the ugly side of the beautiful game for a lot of people - more likely to conjure up thoughts of lad culture and hooliganism.
But over the years, things have changed and the shirts are now very much back in fashion, with some highly sought after and exchanging hands for hundreds of pounds.
This trend can be clearly seen at music festivals.
Some events - including Radio One's Big Weekend in Londonderry and TRNSMT in Glasgow - have previously placed a site-wide ban on football shirts.
