I suspect the problem is that men don't buy women quality lingerie. Crappy cheap lingerie like Victoria's Secret, made with slave labor, is extremely uncomfortable to wear, unsupportive and falls apart after the third wash. It's made for men to look at, not for women to wear. As such it's a veiled demand for sex.
I can't imagine a woman not liking and not wanting to wear quality lingerie. And if there's a question that the man is buying it really for himself, give a gift card, then she can pick what she likes and in what size. I know I would be thrilled if I got a LaPerla or Wacoal or Agent Provocateur or Wolford's gift card.
Well technically only Wacoal makes my size. Incentive for me to lose weight! :D
