I love the colour red, but scarlet sometimes seems a bit too vivid. Personally I'm fonder of slightly darker reds, or even wine-coloured. Why are you considering getting just one bra? Perhaps I'm indecisive, but I'd get maybe two or three fairly inexpensive ones in different colours, and switch them around according to mood.

Something I've wondered is whether men even care about the colour, design, etc. of the bra. Lots of women's websites stress the importance of lingerie. However, with the men that I've been with, the clothes come off too quickly for anybody to really notice what the other person is wearing. I think lingerie can be very, very pretty although my boyfriend says that he simply doesn't "understand" them. This made me lazy, and deterred me from ever investing in lingerie for sex...
