Size medium, brand new, never worn, one piece, long-sleeved, zipper up, bathing suit. I bought this size, and a smaller size, hoping to keep one that fit the best, and then send the second one back. Sadly, the shipping costs were as much as the cost of the bathing suit. This is a great alternative to keeping the sun off, but not wearing a wetsuit. The size in medium, and would fit a size 6-8. I'm a true size 4 and this is too big for me.
