What's the most you are willing to pay for a shirt?
I only buy good quality shirts (60% cotton and up) ,and I try to avoid 100% polyester, nylon etc.
My price range is 12 bucks or less for a basic shirt. If it's more elaborated my limit would be at 25(ideally I would prefer less than 20), and on really rare cases up to 30 but it has to be an EXTREMELY beautiful and unique shirt that I'd probably regret it if I don't get it.
