Neither one is quite my style. I'd prefer something a lot more unique and more daring, but if I were to pick between the two above, I'd choose B because it's more versatile (can either be worn in the bedroom or underneath day clothes).
Gonna go with A because it's the most different from what I usually wear so I think my FH would appreciate that. Though really, he'd like either, and I wouldn't be wearing either for long
B. Could be worn again, looks gorgeous and when it comes down to it looks more comfortable to wear but also easier to take off when the time comes. : p
