There is a sports or t-shirt bra that are not noticeable. You can wear a regular bra with an oversize shirt or top. As a man that wears a 42C for support I get such relief for pain and comfort that I really do not care you sees the Georgia Football 2022 Southeastern Conference Champions T-shirt besides I will buy this bra straps or can tell that I am wearing a bra because it comes down to no one’s business but my own. Stay away from underwires….DEFINITELY NOT CONTOUR CUPS…….and padded cups. Just a completely soft cup bra. Easy in cooler weather with a jacket, very tricky in hot weather. Probably will show under T shirt or short sleeve shirt. Try it, It’s fun. An unpadded sports bra or an Aaahhhh bra. They’re fairly cheap. A bandeau bra has no straps and modest padding and I wore them plenty of times and was never busted. Wearing a looser shirt hides the contours fairly well. If you have to wear a button shirt for work I wouldn’t bother with any, too easy to see.
