1920s cocktail dresses

Looking for a very simple prom dress. This will be my 4th prom so I don't want to spend anymore than $100. Looking for something form fitting. Size 0-2 but if the dress is a corset it can be up to a size 4. Also not willing to buy a dress that needs to be shipping so Missouri people only or people willing to meet near St.Louis MO 1920s cocktail dresses
