Worn and washed once only (bought for a travel emergency when my luggage didn’t arrive). 53% cotton, 23% polyester, 22% rayon, 3% spandex. Pit-to-pit 19”, length from collar seam 36”, sleeve length 23”. Dress can be worn snug as a size large, or a little loose and less body-con if you normally wear a small to medium (and it is knee length on me, as I am 5'2"). Great for work with a long blazer.
