If you're looking for a great dress for the base of your costume, this is perfect. Because it's soooo thin, only wear it by itself if you're OK showing off EVERYTHING underneath! But when layered with other items (like a corset and sash as I'm doing for my pirate wench costume), it's a great job.

The neckline elastic has enough pull that you can wear this dress as a wide-scoop neck without the fabric bunching unnaturally, though it does look a little better worn off-the-shoulder. I agree with the other reviewer about length, at a little over 5'8", this comes down to just above my ankles instead of the nearly-floor-length as pictured. However, it is long enough to cover most slip and petticoat options.
