True to size and very cute/sexy.  Thin, costume-like material, but constructed well.  Had a blast in this with white gogo boots at a 70's night.  Comfy and sparkly.  It is bit shorter than what I am used to, so I wore a slip that sometimes showed if I bent over too much, but I preferred that over the alternative!  Husband, of course, kept me in check as far as that went.  But I loved it overall and hope I get a chance to wear it again.  Headband accessory is very nice as well.
