I read the Seller's instructions that this dress runs small so it's best to order a size up. I am 5'8 1/2, and I normally wear a size XL or US 14. Therefore, I ordered a US 16, unfortunately, it's too big. I am impressed with the "fast shipping"; I received the dress early this morning. I really want this dress, the color and style is exactly what I am looking for, to attend a "black tie wedding in 2 1/2 weeks". Therefore, will return the 16 and order a 14. I pray the 14 looks nice.will update oSee full review
