Beautiful geometric full length dress. Crepe material is 100% viscose, with buttons down the front, cinched, elastic waist and slit on the front for breezy. Says US 2 but fits more like a 4 Lay flat elastic waist is 13in across but stretches to comfortable 15in across. 17in from shoulder to waist (sits below the ribs) 41in long (great for tall people!) The open back is beautiful with a sexy but classy feel. This dress is really beautiful and fun to wear as an outdoor wedding guest dress or fun day out. Love it, just outgrew it.
