Save the Queen White Summer Fancy Dress

This is an easy-to-wear summer/island dress. I purchased in St Barths and wear with heels, flats and sneakers - very versatile. It says XL band also S6. I think it is more like a 8-10 in real size. The top has 2 layers so cannot see through; thebottom has numerous layers and the front is shorter that the back.
