Influencer Costeen Hatzi looked like a long-lost Kardashian sister as she posed on a date night with her boyfriend, tennis star, Nick Kyrgios.

Posting to her Instagram Story on Thursday, the 23-year-old showed off her tanned and toned figure in a black three-piece suit to her nearly 200,000 followers.

Mossman’s outfit featured a long black skirt and a black bra that exposed her midriff.

She also wore an open black blazer to tie the look together and was holding a yellow clutch bag.

On her feet, she paired the all-black outfit with a pair of strappy black heels.

The influencer gave off some serious Kardashian energy in the photo as she posed in front of her mirror with full lips.

Her tanned complexion and long dark locks would also make viewers double check that she is not one of the famous sisters.

For a night out, Costeen opted for a glam makeup look with dark eyeliner and sculpted dark brows.

Before their dinner, she also posted a cute TikTok video with her boyfriend, tennis star Nick Kyrgios.

The couple were dressed to the nines while he donned a black tuxedo and a new haircut.

“It was a professional/friendly conversation and then he came to pick up the mirror from Sydney.

“I had no idea this was all a plan, I literally thought I was buying a mirror.

“After that, he moved all his work and training to Sydney and has pretty much lived in Sydney ever since.”
