This is the first wireless bra I've ever had that ACTUALLY like seriously supports my 12F boobs. It's so comfortable and supportive that I've purchased 3 more. The one catch is it seems I have a slight allergy to the metal of the rings holding the straps and get little rashes from them, which has never happened to me before, but it's no biggy. These are amazing under tshirts as they're so smooth, I hate when tshirts kind of crumple between my boobs and these bras stop that from happening. Honestly I can't praise them enough.
