i just got this in thursday! && it's so pretty i LOVE it. but i have a problem. it's a small that i ordered over the phone from new york because i tried on the meduim & it basically fell off. well this one is REALLY hard to get on. it gets stuck right at my thumb knuckle. today i tried putting it on with a little bit of vasline on my thumb & it helped but it's still a tight fit. i'm really afraid that if i gain a couple of pounds i might not be able to wear it. but i love it so much i don't want to part with it. once it's on it fits perfectly but there's no telling how long it will fit & my thumb is sore from trying different ways to get it on & off. should i keep it & take my chances of not being able to wear it or should i take it back?
