On Friday, the 36-year-old reality star took to Instagram with a shot of herself flaunting those infamous curves in a white T-shirt and matching thong bikini.
Kim gave fans a better look at her bikini in a string of waterfall pics shared on her personal app.
The bikini queen also detailed her "Costa Rica Street Style," posting a shot of herself in a slinky metallic swing dress by Paco Robanne and a black baseball cap.
"I wanted to be a bit more colorful when we were on vacay, so I went with this rust-colored Paco Rabanne dress. I wore it with these really old Manolo Blahnik heels and a velvet baseball hat," Kim wrote on her website, along with links for fans to purchase her entire ensemble.
Kim is living a new normal since her scary robbery in Paris last year, and while she's slowly getting back into the fashion scene (she went braless for her husband Kanye West, Yeezy Season 5 presentation in New York City on Wednesday) the mother of two won’t be heading back to France for Paris Fashion Week.
