I say 'go for it!'. I ride a Schiwinn Varsity 'girls' bike, as so many have told me. It has the Mixte type of frame. My problem is that I'm 5'11" with a 29 inch inseam. On a bike that actually fits my torso, the stand over height is waaay to high. I slide off the saddle to dismount and take that top tube where it really hurts. And, if there's panniers on the back, I often can't get my leg over the bags and I sure can't do it over the top tube. The mixte frame solves those problems. I can get on, or around the the bike and the bike is the right size for me. If you like the style, and it works for you, ride it!
