This is a beautiful wrap dress. Im 51 a 38 bust, 33 waist and 41 hips. I ordered and XXL. I wear between a 10-12 but I don't like tight clothes. The XXL suits me well. I could have ordered an XL and it still would have fit well. It is a wrap so it will fit larger bust. The material is nice and thick (not transparent) but still cool for summertime. This dress is well worth the money, the quality is great. If you're my height you will have to wear some sort of heel because it will drag in the back.
