Vanessa has minimal accessories and her necklace, watch, and earrings compliment her dress without overpowering it. Her heels are open-toe, a better choice, and the clutch serves the look as it should......an accessory item only.
See the below items for examples of this......more aptly styled sequined look I've gathered for all you divas.
Adrianna Papell Sequin Sheath Dress with Chiffon Waist
The chiffon waist helps to break up the monotony.
Pleated Frame Clutch $138.00 http://www.bcbg.com/
Silver Twisted Ring Earrings
The above earrings are also understated. They're elegant and chic as well.
