Wow! It looks like Kim Kardashian has managed to get her body back, four months after having a baby. She posed alongside her sisters in a sexy new shoot for the Kardashian Kollection’s special collaboration with UK retailer, Lipsy London.

After giving birth to baby North West, Kardashian, 33, is ready to get back to work with her sisters on their various clothing lines. For her first post-baby photo shoot, the realty star joined her sisters, Kourtney and Khloe, to unveil their Kardashian Kollection line for Lipsy London — and Kim didn't seem to have any problem squeezing back into her favorite skintight dresses for the occasion.

A source close to the project told HollywoodLife.com that the entire production was totally top secret. “The photo shoot for the new collection was done in LA with Terry Richardson, and it was top secret. Khloe will be the one to go to London to promote it, not Kim or Kourtney.”

While Kim kept a relatively low profile immediately following the birth of her little girl, she seems to be easing back to work just fine — and she certainly looks great while doing it, opting for one sexy get-up after another.
