I keep noticing these amazing colorblock dresses by Theory, and I guess I'm not the only one: Forever 21 has a colorblock dress (above right) that looks a lot like Theory's "Whitika" dress (above left). Depending on the strength of your budget (or your willpower), either dress would make a great addition to your wardrobe. Create a simple yet sexy look for that holiday office party by pairing your colorblock frock with black tights, heels—like these spectator booties from Charlotte Russe ($26.99)—and a chic cover-up—like this knit shrug from Forever 21 ($17.80). Add your favorite accessories and you'll be the best-dressed girl in the room. What do you think?
