In whatever the Kardashian ladies wear, all three seem to look fabulous, flawless and beautiful. Even though Kim just had a baby, she still looks gorg! But, this isn't about Kim; rather, it involves Kourtney Kardashian, who gave birth to second child, Penelope in July 2012.

According to the Huffington Post, on Tuesday, July 23, Kourtney flaunted a black and white string bikini at the Setai hotel in Miami. She wasn't ashamed to bare her beach body while hitting the beach. Just a week before this, Kourtney wore a one-piece bathing suit, but transformed into a two-piece queen. Even though ”It took me twice as long as last time but I feel healthy and really much better about it,” Kourtney mentions on Celebuzz, she still put forth the effort!

After almost a year, she got her figure back.

"I gained 45 pounds with Penelope," she told US Weekly in January. "It was harder to lose weight the second time around."

We've seen some Keeping Up With the Kardashian episodes where with either Kourtney or Scott criticizing her weight. So, she wanted to work harder!

To get her original body, she worked with trainer Tracy Anderson, doing 90-minute dance-focused workouts and eating small portion meals, says US Weekly.
