I am also larger in the chest area and I am uncomfortable not wearing a bra because it gets sweaty underneath them. Sometimes it doesn’t, but I live in Southern California and i’m more likely to be hot than cold, and when any flesh is pressed against any other flesh for any amount of time (like under my boobs), it gets sweaty. Sticky. I hate that feeling. But I have found a couple bras that are extremely light, very soft material, don’t provide any support but they do help with my boob sweat issue.
