Kathryn M.wrote a review of Castelli Velocissima Short - Women's on January 21, 2018
Familiarity: I returned this product before using it
Take this all with a grain of salt because I've never worn a chamois when riding and only tried this one on in the house. I ordered a small based on other's reviews, but it was still too small. My waist is 27 and my hips are 34.5; I'm 5'1" and weigh approx 110 lbs. They fit fine everywhere but the waist (too tight). This is the part to take with a grain of salt: the pad felt too stiff and like it would rub when pedaling.
I hate giving it stars since I never actually wore it while biking, but that's not an option.
