Another one very happy with the Selle Italia Lady (Ldy) Gel Flow, but it's very similar in shape/size/padding to a Terry Butterfly (which I have on my mtb), so if the OP doesn't like a B-fly, she won't like the Gel Flow. It's a very individual thing, and your overall body size has nothing to do with it. I'm a little thing with narrow hips, but I still like my wider saddles!
