I was a bit confused with all the reviews here. some said this runs small and others said it runs big
i decided to go to the store and try it. i'm 5'6 and 112 lbs. i'm usually size 2 or xs.
when i tried the blue one, xs is very tight on the arm and i would have to size up if i ever want to wear a sweater underneath.
however, when i tried the beige one, xs fits me well with some room for sweater.
either one is beautiful. great quality as you would expect from this brand.
