Here are some ideas: A White Bedazzled bracelet or ring would be tons of fun for a party or a day on the town. Check this "Dazzle Cuff" out from Gilt's Miriam Salat Jewelry Sale. A little pricey for me (even after the 60%+ discount) but I'm sure you'll be able to find a pretty sweet knock off at Claire's or Aldo in about 5 weeks. Speaking of awesome, cheap finds, check out this "pave" ring from forever 21. $5.80. That's what I'm talking about. If this thing doesn't catch your eye from across the room, I don't know what will.
Another summer must have: A JEWELED WHITE WATCH. Make it happen. Below is an example of my idea of an ideal white summer watch . BUT if you're on a budget, try this one from Arden B. for $29, or head to Aldo Shoes and snab this $35 flexi watch. 5x the flexibility and 1/9th of the price:)
