Well, in case you were being serious, the point i was responding to was the 'if it's obvious to everyone that she's gay, then wearing a shirt with a shirt boating about it is somehow a little cringe'.
My point was both that just because someone looks stereotypically gay doesn't mean they are, so it's fair to wear a shirt proudly admitting it, even if it is a little over the top. The earlier comment about it being similar to sometimes Uncle wearing a shirt offering 'mustache rides' is completely off the mark since that is more of a crude case of a man trying to either boat about his manliness, or defect implications that he's gay.
These shirts are basically leaning into the 'f-you, this is who i am', unless they were specifically wearing them to a lesbian meet up hoping to impress other girls with the words on their shirt. If that were the case then it would match almost exactly to the mustache rides example.
Pretty much 'anything' clothing. I guess if it's a clothing brand of good quality and there is no choice except to wear it with the logo they stick on it might be an exception, but anything outside of that is basically paying to belong to some club with basically no membership requirements except spending money.
