Stars are making a splash in dresses decorated with fish-scale designs. Brittany Snow wore mermaid-inspired Marchesa to a recent awards show. "I loved all the beaded detail work," Snow's stylist Nicole Chavez said of the frock. To avoid being mistaken for a denizen of the sea, choose a dress in a neutral shade. "In Brittany's case I think the trend worked well because [the dress] is cocktail length and has the delicate contrast of the nude tulle," says Chavez. Glamour, ahoy!
