The 36-year-old reality stepped out for dinner on Wednesday night with her close pal, Larsa Pippen, at Craig's in West Hollywood, California, rocking a super sexy lace burgundy top. The low-cut, sheer style made it obvious Kourtney skipped the bra for the night, and it also showed off her enviably slim stomach.
The Keeping Up With the Kardashians star completed the look with her favorite accessory -- a black choker -- and wide-legged black pants, which look pretty similar to the pair she was rocking earlier this month during a night out with her younger sister, 20-year-old Kendall Jenner.
Clearly, Kourtney's feeling herself these days, and she knows it. The mother-of-three Instagrammed three close-up shots of herself in the sexy top on Wednesday, revealing her look was for an upcoming episode of Kocktails With Khloe.
... Looking good, Kourtney!
Earlier this month, a source told ET that Kourtney has officially moved on for good from her ex, Scott Disick, even "putting herself out there" and going on dates.
"She is the happiest she's been in a really long time," the source said. "This breakup has really showed her that she needs to focus on herself. She's spending a lot of time with her girlfriends, is planning dinners and nights out. She's happy and glowing."
During her appearance on The Ellen DeGeneres Show last Friday, Kourtney explained her current relationship with Scott.
"We're not together," Kourtney said, slamming rumors that the two have rekindled their romance. "I feel like every day is different, but we're totally getting along. Like, we have three beautiful kids together."
"But, ya know, he's family," Kourtney continued. "He'll always be."
