So, we've found the basic '90s combat boots for cheap, a lavender top (have your tailor crop it if you've got the cash and abs), and a plaid school-girl skirt, but the details are what will make this costume click. Attach the Jonathan Adler pill keychain to your mini, a boombox iPhone cover to your celly, and don't forget to place a pic of the object of your character's obsessive desire in her nametag. Toss on a long black wig (unless you've already been blessed with thick, ebony tresses), et voilà, you'll be a dead ringer for lanky Liv!
