Christian Louboutin's "Un Bout" pump is one of the most popular shoes in Hollywood right now, with Brooklyn Decker, Jennifer Lopez, Ashley Madekwe, and Emma Stone all scooping up the crimson version of these illusion heels. We love how Lopez and Stone defied the matchy-matchy rule by pairing the heels with scarlet dresses in the same color, and also how Decker and Madekwe highlighted the splashes of red in their ensembles with Louboutin's design. While the strawberry shade was popular for spring (and sadly no longer available), Louboutin rolled out a new black version for fall, complete with spikes and studs ($1,435 at net-a-porter.com).
