Anastasia ‘Stassie’ Karanikolaou bares her tummy in a black sports bra and skintight leggings in LA

Anastasia ‘Stassie’ Karanikolaou was full of laughter as she stepped out with friends in West Hollywood on Tuesday.

The 25-year-old influencer was clad in a black sports bra from Set Active, which she teamed with leggings.

Kylie Jenner’s BFF wore her dark hair in a center part and pulled back with a brown banana clip.

A few strands in the front fell over her makeup-free face and she slung a black designer purse over her shoulder.

Stassie skipped earrings and other jewelry as she wore a pair of white tube socks with pink and white sneakers.

Her leggings were high-waisted and exposed her taut upper abs as she walked alongside a redhead friend who was similarly dressed.

The internet sensation protected her eyes from the glaring Southern California sun with rectangular black shades.

She was joined by her close pal Victoria Villarroel, who rocked a baby blue romper for their afternoon out.

Later on Tuesday the entrepreneur appeared on Instagram to tease new YouTube content with her followers.

She uploaded a seconds-long reel demonstrating her ‘go-to everyday makeup,’ which showed her applying her favorite products.

Karanikolaou was glowing as she began the clip bare-faced and showing how she fills in her eyebrows.

The blue-eyed beauty described what she was doing in each step, keeping fans engaged.

The finished product showed her dewy and radiant, flaunting her perfectly-applied cosmetics.

The YouTuber’s cheeks were rouged and she smiled softly, showing fans her lipstick-coated pout.

Her dark hair spilled around her face in a center part and long, immaculately textured waves.

She wrote in the caption to her 11 million followers, ‘new youtube vid live. link in bio.’
