I would be more likely to do it for my spouse...but not for a boyfriend.
The last guy I dated was lingerie crazed. In the few short months we dated he bought me no less than 40 pieces of intimate apparel. He was clueless too. Everything from extra small to 3X, it was like he just went into the store and grabbed anything that he saw. Most were soooo tacky, neon pink thongs and leopard print cut out teddies. Just awful and cheap.
I picked through what I liked but maybe it was 2-3 pieces. Since they are non returnable I have 3 bags full of unworn undies and bras etc... and I won't wear any of it for him.

And you know what? He was a little dissappointed but in the end it didn't matter.

He also wanted me to wear wrangler jeans in the worst way, but again I wouldnt. And again he got over it..
