"I wear a Large (8)..I purchased this in a size 8, sometimes an 8 runs a little small, due to the cut and I have to size up, but this top, the second I tried to slide it up my arms, I knew there was a problem, The entire cut of this top is WAY too small to be size appropriate, I would say that the size 8 ran closer to a size 4/6 with pencil thin arms..."
