Clear seems to be in with all the recent sightings of clear shoes and bags (which I don't really care for). I love the look of clear in jewelry and nothing beats this simple, clear lucite thin bangle from Intuition ($20). It will go perfect with any outfit.
These clear jewels will match anything you have on too:
Oversized Lucite Choker ($45 at Intuition)
Fragments Small Lucite Earrings ($30 at Shopbop)
RJ Graziano Clear Long Necklace ($75 at Nordstrom)
RJ Graziano Clear Ice Cube Charm Bracelet ($75 at Nordstrom)
OSS Necklace ($80 at Tadam Jewelry)
