The pose is just aces especially with the positioning of her feet but what really draws me in is the way it looks like there is either a smile or a frown playing around the corner of her lips.

Yeah I'm a guy and of course the fact she's scantiliy clad counts for something but the other things just overpower the fact that she's standing there in her undies. So much so in fact that I'd love to see a cropped tighter shot of her head and shoulders from this picture.

Anyway, great work all around, solid photography with very beautiful models.
