The fit is really nice (its not too tight under your arms), and the length is great on me (Im 51, so it may be shorter on you)
Our Womens 20s Charleston Flapper Costume ($50.95) is the period-accurate one: a champagne velvet dress cut to the era's true knee length, black fringe running in rows across the skirt, black lace marking the dropped waist, plus a jeweled feather headband and elbow-length gloves in the box
Women's jackets are fitted generously
For a more intense appearance, choose a gothic wedding dresses white
Suggest the formality level, since guests should understand that a masquerade calls for formal attire, with gowns for the girls and dressy looks overall, rather than casual party clothes
Alternately, pair the dress with something more modern like a button-inspired brooch, or think outside the box with one made of ribbons or feathers
