This is the "Charleston Flapper", a beautiful, yellow poly, and gold trimmed, straight line dress, with sequin shoulder straps.
The dress has a sheer overlay on either side of the dress, that has a gold glitter swirl design.

The upper edge is elasticized, and the dress is trimmed with gold sequin, sequin fringe and a faux pearl.
It includes a matching gold sequin and ostrich feather headband.
Photos 3 & 4 show this dress with a black boa and a blonde wig, sold separate.

Sizes measure as follows:

                  Bust         Waist         Hip
Small-      30"-32"   28"-30"    30"-32"
Medium- 32"-34"   32"-34"    34"-36"
Large-     34"-36"   34"-36"    36"-38"

*Note- The measurements are a bit conservative. There is some stretch to the yellow fabric, which is the base of the dress, so you should be able to allow for a 1/2" or so more, but bare in mind that a Flapper dress should hang straight, and not fit too tight.
