Step back in time to when the full princess-cut ballgown was in vogue. These vintage style 1950s formal dresses, 50s evening dresses and 1950s evening gowns hint at the past while embracing the current modern trends. Silk or satin, chiffon or tulle full skirt ball gowns over voluminous petticoats create the ballerina evening fashion. Long, slender, strapless column dresses were another 1950s formal dress favorite, especially in black. Shorter sexy wiggle dresses or tea length swing dresses in satin, organdy or velvet were for semi-formal cocktail parties. You can find more cocktail party dresses here.
