A statement-making necklace is such a quick and easy way to update your look. It's no secret that people are trying to pinch their pennies these days, and investing in a standout necklace can make wardrobe pieces you've had for years look brand new. At the BET pre-party, Jessica Alba rocked a simple white tee and black blazer combo (worn with cropped pants). On its own, the outfit was nothing special, but courtesy of the gorgeous multi-chain Gemma Redux necklace she sported, she looked totally fashion-forward and on-trend. The multi-chain style is a huge right now and can add just the right dose of edge to your look. Throw one on and toughen up a sweet floral frock, upgrade a basic jeans-and-tee look, or add some glam to a classic LBD-- the options are endless. Check out my slideshow for 5 necklaces similar to the one worn by Jessica.
