This dress is a lovely champagne color with light material (very comfortable for summer weddings) and ruffled sleeves. There is no zipper, it is elastic around the chest and fits a variety of sizes well. It is listed as an XS, which the website says is best suited for sizes 0-2.
Alterations: Minimal. The shoulder straps were taken in less than 1 inch and it was hemmed slightly. For context, I am 5'2 and was wearing 3-4 inch heels.
