Kim Kardashian

But beauty is pain, right?

Kim and Kourtney Kardashian were spotted at Sielian's Vintage Apparel on Melrose yesterday afternoon, and the reality TV starlet squeezed into a sexy (but somewhat restricting!) blue frock as the paps snapped away.

We're not sure if this dress was the winner, but Kim did walk out of the store with a shopping bag and a smile on her face, so it looks like she was somewhat successful!
