Where Can I Find...Leighton Meester's initial necklaces?

Leighton Meester with Alex Woo Little Letters inside InStyle! Gossip Girl's style setter flipped for this diamond Little Letters necklace by designer Alex Woo -- the "BW" is for character Blair Waldorf's initials -- so she snagged an "L" for herself. Initial letters come in sterling silver, 14kt gold, and diamonds. You can further personalize your jewelry by combining several initials on one chain to spell out a word.
