A sparkly party dress is the fashion savvy girl's ultimate Christmas party weapon. A cooler alternative to the LBD, they are a sure-fire way to get noticed and these glamorous stars know that when they really need to shine, sequins are the way forward. Alicia Keys dazzles in an elegant Armani gown while Eva Longaria opts for a glitzy version by Kaufman Franco (the designer was also responsible for her wedding reception dress). Trend-setter SJP looks a million dollars in an electric blue Alice & Olivia shift and beauty Cat Deeley in French Connection proves you don't need an A-list salary to work this look. To prevent styling overkill, keep your hair natural and accessories fuss-free, and don't forget your dancing shoes!
