It measures about 20" thru the belly area. It's kinda a body-hugging type dress, so it was hard to measure. I had the strings tied in back when I took the pic. Length is 37" from top of collar. 50% cotton, 45% rayon, 5% spandex. 3/4 length sleeves. It is in excellent condition since I didn't have too many places to wear it. I probably only wore it 3-4 times with both pregnancies. It has a cute navy and light blue retro print, it's kinda hard to tell from the pic. It would be really cute for a wedding I think, and I can get it out to you by Tuesday if you want it.
