Kim Kardashian made sure she stood out on her first night out as a single lady  in a skin-tight dress  and nothing on her ring finger.

Kim — along with her sister, Kourtney, gal pals La Anthony and Stephanie Shepherd and Jonathan Cheban for good measure — hit up Matsuhisa in Bev Hills and Kanye West’s ex looked ready to mingle.

Though she wasn’t wearing her wedding ring, Kim was blinged up just a bit to accessorize with a super cool neon green dress … and she looked pretty happy with her friends.

Of course, Kim’s outing comes just days after we broke the story … she filed to divorce her famous husband of nearly 7 years after several turbulent months that started right around the time he announced his run for president.

As we told you … everything seems to be amicable — Kim’s asking for joint legal and physical custody of the couple’s 4 kids, there’s a prep neither side is contesting, and Kim and Kanye are committed to co-parenting.

Clearly .she’s still committed to living her best life too.
