I was impressed with this purchase both due to the sizing and the packaging.
As I liked the style of the top, but they only go up to a size 16 I took a chance and bought this size to see how badly it would fit. It actually fits me quite comfortably, with no stretching of the front lacing, and I have a 44inch chest measurement. Due to the nature of the material which is quite stretchy and slinky, I believe that a range of sizes could wear this top without distorting the cut.
I was also impressed that the top came nicely wrapped in tissue paper inside its box, with a free lollipop!
