Great Summer Dress
Size: X-Small, Color: White
This is such a pretty dress. I'm pretty small--a size 0 J Crew or 00 Loft--and the XS fit me with some room to flex. It's very pretty on, not see-through, and it holds its shape nicely over the course of a day. A perfect summer dress!

See through.
This dress is outrageously thin and cheap. I can’t believe it’s priced at $90.00. This dress is horrible.
