Nice top, but...
I bought this in a size M, I'm a size 12. It fitted well on the body, but was long on the arms-and I'm 5'7 (I've found this to be the case with other Skinnydip long-sleeved tops I've bought). The top is also slightly cropped on me too. I didn't think it suited me well, so I have returned it.
Overall, the top is nice and good quality. However, the sizing on the arms and the actual length of the top wasn't right for me.
