But yesterday she opted for a different look entirely - concealing her belly in a high-waisted skater dress as she headed out for a business meeting.
Instead, the reality TV star, who is expecting a baby with boyfriend Kanye West, put the emphasis on her growing boobs and her toned legs, in the thigh-skimming black number.
Kimmy K completed the look with a pair of skyscraper black and gold heels, a simple black clutch bag and her hair in her new favourite top-knot.
The 32-year-old, who is expecting her first baby this summer, appeared to be channelling little sister Khloe Kardashian, who showed off her own legs yesterday in a tiny leather skater skirt.
And it's not surprise that Kim wanted to show off her toned legs too, after all she is making sure she exercises throughout her pregnancy to keep in shape.
She tweeted earlier in the day: "Morning twitter fam! Early morning workout!"
Kim talked recently about her struggle to get used to her new boobs - which have gone up four cup sizes.
A source told heat magazine: “Kim loves her curves. But she’s upset that nothing in her wardrobe fits her any more.”
Apparently the reality star has reportedly gone from a 36D to a 36G since announcing her pregnancy.
