J.F.
As a large chested woman, I would have to say there is no such beast! I wear a 36F and buy my bra's at Cacique. They do have some wireless bra's available, but I have never tried them out. What I can tell you is that I get more compliments on how perky my breasts look when I wear my Cacique bra's. They are expensive, but go on sale a lot AND you can find coupons. I wear the smooth balconette. It has a little bit of thin padding for shape and excellent bands and straps. They are the most comfortable bra's that I have ever worn.
Good luck and happy shopping!
