bras are not uncomfortable
even underwire bras, like i don't understand why people say that they're so uncomfortable and they hate wearing them. i guess people mostly just say that it feels really nice to get home and immediately take your bra off and people will even say that they do it literally as soon as they get home, first thing, and that tells me that you think bras are uncomfortable, or at least a lot less comfortable than just not wearing one, and i just don't get that.
i saw a clip from a movie or show or smth (where the lady who plays regina george is the mom which feels really weird) where a mom takes her daughter to get her first bra and when she puts it on for the first time, the mom says "how do you feel?" and the daughter says "i can't wait to take it off" and the mom goes "welcome to womanhood" as if immediately wanting to take your bra off as soon as you put it on is normal. and she was wearing a training bra, so like??? there aren't even wires????
maybe everyone's just wearing their wrong bra size. if you hate the way your bra feels, take your measurements with no bra on and calculate your size and compare it to the bra you're wearing. there are websites that tell you how to do it, it's not hard, you just need a tape measure.
