My wife is "curvy". She has tried a lot of different CCW methods. Under-bra holster, it works but not great and really depends on what kind of bra you wear. She is a 36C but generally wears non-underwire bras. These did not support the weight of her G43 very well, nor was it very comfortable. She had to,fuss with it too much. OWB does not work with her wardrobe or shape. Neither does IWB unless it is SOB. The belly band worked, but is too hot and tight for summer wear. She has settled on purse carry. Found a nice leather one that is not too fancy looking but very solid. The strap is not going to break easily if someone tries to rip it off of her. A lot of carry options for her really centered on making wardrobe style changes that she was not willing to do. Good luck!
