Jupe en cuir à pression sur le devant

I am 5'2" and 105 pds. I am a zero in most brands. I overnighted this skirt for a event this weekend and was thrilled by the look and feel of this garment upon opening it. But, when I tried it (fit was good!) on and sat down, every snap popped opened! I walked and the snaps opened! I am incredibly disappointed with this purchase and the low quality of the snaps. I will think twice about ordering Ready to Wear from Coach again.
