Katy Perry is known for her bright ensembles and stage outfits, but ladies can learn a thing or two from the pop star when it comes to cocktail dresses. Navy blue is not only a hot color that's trending nowadays; the hue is also known for its slimming properties, especially when under bright lights. If you really want to splurge on a dress for a special occasion, the Alexander McQueen Wool-Silk Knit Dress or the Marchesa Strapless Print Ruche Lace Dress is perfect to hide unwanted curves and stay classy at the same time. If under budget, the cute Navy Star Flare Dress by Dorothy Perkins or the Parker Polka Ruffle Dress is the right combination of fun and glam fit for any occasion.
