which factor is most important in sexy lingerie?

[Tury]

My ideas might be a bit subdued, but I like it to be just before the line of uselessness. Meaning that, while being sexy, it can still fulfill its use as underwear. Essentially, it doesn't give away so much that there's no reason to have it in the first place.

From my perspective, anything, lingerie included, should display curves. But since it is lingerie, the curves should be displaying it using bareness as a factor. For example, the bottoms could be a boyshort style that shows at least some cheek. Not MOST of it but probably around 15-25% of your butt cheeks. THAT shows the curves. Then followed by some that displays the tummy and the sides and sides are where curves are at.

Also, I don't like red lingerie. Light pink or black or even both seems to work best for me. No odd colors like purple or brown as well.
