This Marilyn Monroe style maxi dress has a deep v-neckline with o-ring clasps to hold the dress together in the front and on the side. This light weight, long A-line flare maxi dress gives a sexy bare back that ties up in the back at the waist. If you wear a size 14-16 then you can wear the large. The dress is light weight and gives that beach type flow. Made of 100% Polyester.
