Cute slip style flirty dress with one adjustable strap that can be turned into a bow 100% poly, the shell does not stretch but the lining does So I believe this dress is actually y2k from Forever 21, just based on the fact that I have never seen a F21 tag like that, I've never seen and F21 side tag like that, and the materials seem to be of a higher quality than the current F21 HOWEVER, I am not certain. I mean I couldn't find this particular tag anywhere. So if you do know about this label and have information on when its from, please let me know in the comments. I will refrain from labeling it as vintage until I know for sure The left strap (the one on the right in the photos) is the one that is adjustable, and you really do have to make sure its secure when you wear it. I once wore this and just had the strap in a bow, I took my jacket off and the hole strap had slipped out completely. After that I stopped wearing it as a bow and just tied a knot there instead This dress is fully lined Excellent used condition, no flaws Size: small, fits true to size Bust: 16 in across Waist: 14 in across Hips: 17 in across Length: 35 in
