Why is Blink merch so ugly?

Genuinely the worst merch for any band I've ever liked. I've been to 5 concerts now and every time I go to the merch booth I have to choose the shirt I dislike the least rather than my favourite.

"Which one won't make me look like a 13 year old that just blew my $15 allowance at Target?"

Poorly drawn bunnies, mid-2000's graffiti style prints, awful sex jokes, etc.

As someone in their 30's I'm genuinely embarrassed to wear my favourite band's merch and I can't be the only one??
