Yeah I know it's kinda too late to do anything about Valentine's Day. Sorry I'm a day behind, I had my own celebration of Valentine's Day too, you know. *wink*. For me, Valentine's Day only rings two bells: Victoria's Secret and Agent Provocateur!!
Here's my pick:
I always like them with a vintage and sultry but not too girly touch. Lace is quite crucial at times. Although yeah I have to admit that the last one, the balconet push up bra, is a little bit girly with its fuchsia pink twist. But hey, there's nothing wrong with embracing the feminine side of you. The first two is from the Virgins Collection by Agent Provocateur and the last two I found under Sexy Lingerie by VS.
