Pleather zip up halter XS faux leather

I ordered this in both S and XS , the Small fit me so I keep it but the XS really tight! I have worn the Small like 30 times and its held up great. Do not put in washer or dryer, hand wash. My measurements are 36b 28 waist, 35 hips, 115 lbs. So for this size i would recommend being up to 34-26-34, it has a tiny bit of stretch since its not real leather but the stretch is a bit more in the breast cups more than the waist. Hope this helps!
