need help with what to buy w/ christmas money!!

idrk if i wanna buy trip pants or band t-shirts/sweaters but im worried the trip pants r gonna be super uncomfy since im buying them online and i don't wanna spend like 200 on pants i won't wear because specific clothes materials have a huge sensory impact on me which sucks but i also don't wanna buy an ass ton of shirts and sweaters with no bottoms to go with it so idk which one i should pick, in the end i need to save money and the easy option WOULD be to buy a mix of them but im indecisive when it comes to mixing up both things i want (if that makes sense) and i feel sickk when i spend too much money (idk i get a really bad gut feeling after lol) sooo yeah any suggestion would be helpful, thanks !! xoxo <3
