There is just something incredibly sexy about a one piece, even a plain solid coloured one. I've never been able to put my finger on why. I love bikinis, especially with less coverage at the back, but a high cut one piece is what really does it for me.
This is Harmony, one of the latest Wicked Weasel models. You can see that she spends more time wearing a bikini than she does a one-piece, but when she does put on one of Wicked Weasel's nasty open mesh one-piece suits, the results are pretty spectacular!
