Should band t-shirts be reserved for fans only?

Summer means festivals, catching some of your favourite artists and, if you're lucky, a bit of sunshine.
But it's all about the music, right?
Not quite. It's also a chance to rock your favourite band t-shirt, whether it's one you've just bought from the merch stand or one that's seen better days.
They used to be a way to signal your impeccable taste, but recently more and more High Street and fast fashion brands have been selling music t-shirts.
Primark recently released their latest range including Green Day and The Rolling Stones, and other fast-fashion brands such as H&M and BooHoo - which released a collab with punk band The Offspring, have been getting in on the action.
You can usually get them for a fraction of what you'd pay at an official merch stall, making them more accessible for a lot of people.
But there can be a lot of snobbery around them, particularly if they're worn by someone who's not familiar with the musician on the shirt.
Does it actually matter, though?
There's probably no-one better to ask than the bands, so BBC Newsbeat trawled through the mud at Festival to speak to and up-and-coming acts to find out what they think.
'If you like it, wear it'

Pop-punk band Busted, who released their first album in 2002, say much has changed since they got together.
Bassist Matt Willis says it's easy to get hung up on what people wear, but says: "We've never really followed fashion, we've kind of just done our own thing."
Frontman Charlie Simpson says he wouldn't personally wear the designs of a band he doesn't know, but doesn't care if other people do.
"If you like a band logo, then power to you. Who cares":[]}
