I just got mine. The small falls a bit shorter, just like Allicat's. I guess I could not make up my mind and ordered the black in medium. That one is quite long in the back. They are both fine, I guess, depending on how you style them. The small would play nicely with both pants and skirts, whereas the medium would be a tad long for skirts.
Anyhow,they might be a no go for me. The zipper in the back highlights the tuckus too much, plus the line does not lay flat like on you gals, mine is taking quite a detour up the mountain, you know.... Jejeje....
I will post K/Rs on my NAS items sometime tomorrow.
