I don't mind if she wears something that is a general dark shade, or something light or white.  What I don't really care for is red.  I once met a provider for our scheduled session in a bar and she was wearing bright red and stuck out like a sore thumb.

But seriously? Any color tiny dress w/heels, and sans panties.

but your skin tone has a lot to do with what works  best for you. Oh, animal prints do it for me as well.

Black or white lace on blondes, red silk or satin on red heads (love to play with fire),  blues on brunettes, simply because so many brunettes have left me playing the blues.  But my favorite thing to see on a woman is me.

Black blue white or wine-red.  Other colors very rarely.  Yes it matters quite a bit on her.

Hahahahaha omg!! I just choked on my breakfast....

Nude color cuban stockings with a pair of black 5" classic ankle strapped pumps...  Tan garters and sheer thong (1 1/2" wide in front) with a tan shelf bra and a pearl necklace...

Depends on skin color. But, I love Royal blue.

red or white!
