Kim Kardashian shares very sexy bikini selfie on Instagram

Kim Kardashian spoke of her joy after she revealed that she's managed to shrink her waist down to a mere 24 inches.

And on Tuesday, the 37-year-old shared a selfie, while wearing a very sexy bikini, as she showed off the results of her hard work.

Kim wrote: “Forgot to post this last night”

The basic bathroom was minimal in style, save for a random coat hanger which was perched on the sink.

Her eye make-up was very dramatic with a bold smoky dark blue lid and strong brows and she wore an overstated blinging wide choker.

Posing in a bathroom, Kim sported short platinum blonde locks for the snap as she modelled a skimpy black triangle two-piece.
