This is a hip and stylish long sleeve dress by Jamison Boutique. Feels like all or mostly polyester. White dress with soft pastel striping in pink, blue, green, yellow, and purple. Seven button front with nice frilly detail on the front, and a button at each cuff. Hidden pocket on each hip! Slight poof on the shoulders, matching belt. Sheer, thin, and light weight. It's in amazing shape with years of life left! The tag says size 6, but here are the exact measurements. (be sure to reference the last photo to see how I measure dresses)

Here are the measurements:

Bust 19"
Waist 18"
Hips 20"
Sleeve 23. 5"
Length 47"
