Kim Kardashian flaunts her figure in tiny bikini belonging to Kylie Jenner

Kim Kardashian loves flaunting her famous figure on social media – and the new mom appears to be more body-confident than ever.

The reality star posed for photographs wearing a teeny bikini that belonged to her 16-year-old sister, Kylie Jenner. She posted the bodacious image to Instagram on Wednesday.

Proudly showing off her toned, post-baby physique in the black Lolli swimsuit, the 33-year-old captioned the snapshot: “Yep, stole Kylie’s bikini… she’s not getting it back.”

The Kardashian clan are currently in Miami, staying at the luxurious Versace mansion, a beautiful 10-bedroom home which sold for $45million last year.

Earlier in the day, Kylie shared a number of photographs of herself wearing the same cutout bikini including one taken in the pool of the mansion, which was lovingly renovated by its former owner Gianni Versace.

Kim has worked hard to get back in shape after welcoming daughter North West in June – and she now has her upcoming wedding to Kanye West as an added incentive.

The star previously said that gaining weight while she was pregnant was “the greatest challenge of her life”. And she told chat show host Jay Leno in October that the cruel comments about her weight while she was expecting “really hurt my soul”.

Kim and rapper Kanye are set to tie the knot in Paris on 24 May. The power couple are hoping for a “super small intimate wedding” with around 150 guests.

“As we go along, we’re realising we want it to be smaller and more intimate than people are imagining and thinking.” Kim told Ryan Seacrest.

She also revealed that her husband-to-be has been very involved in the planning process – although there are some details he doesn’t want to deal with.

“There’s certain things where I’m like, ‘I know you’re going to hate the seating chart, so I’ll take care of this’,” Kim said. “And then there’s some things that are really important to him. (But the) seating chart is like death!”
