Ditto objections to the childish colors and patterns. I am a woman, not a girl.
Problems with fit: I am tall, big-boned, hourglass-shaped (long torso, short legs, big difference between hip and waist), and run to muscle. Men's clothes aren't built for this, nor are most women's. Anything that fits the hips is generally three inches too large in the waist. Anything that fits close to the torso (which I prefer) is too tight in the shoulders and arms. My problem with women's clothes is that they just aren't "womanly" enough. Everything appears to be designed with Alyssa Milano in mind.
(Shoes are beyond useless, but that's not a woman-specific problem. NOBODY makes ANYTHING in 8.5 EE/B for either men or women. I just figure I'm a mutant, and let it go at that.)
I ride a standard fit mountain bike. Women's bikes don't fit.
Pearl Izumi is great for the shorts, but I haven't yet solved the jersey problem yet.
