The only tag on this dress says dress.com and there is no other information. I would guess it's 100% polyester and machine wash cold. It's got some stretch to the fabric and I would say is a size medium. Model wears a size 6/8 in dresses.
It's a great basic dress for costuming or fun since it's got so much sparkle to it!
