Kylie Jenner’s BFF Anastasia ‘Stᴀssie’ Karanikolaou flaunts VERY tiny waist in a skintight workout set as she heads to a gym in West Hollywood

Anastasia Karanikolaou was spotted on her way to a workout class in West Hollywood on Thursday.

The 25-year-old social media star flaunted her flawless figure in a GLOWMODE workout set, which showed off her toned arms and flat stomach in the warm California sun.

The beauty – who recently showed off her new collaboration with the brand Cupshe – opted for a navy blue set.

She wore her long brunette locks up in a high ponytail in preparation for her upcoming gym session.

The model accessorized with a pair of rectangular-framed sunglᴀsses on her makeup-free face and a simple pair of silver earrings for jewelry.

Over her shoulder, she slung a small black purse and carried the keys to her car in one of her unmanicured hands.

This gym outing comes soon after she unveiled her new spring campaign with Cupshe, the swimsuit and fashion brand.

The long-time best friend of Kylie Jenner shared with Dailymail.com that she is thrilled to be working with the brand.

‘I’ve always loved swimwear and trying new styles, so when I had the opportunity to partner with Cupshe, I wanted to really focus on the fit and versatility of styles,’ she shared.

‘The Cupshe team has been so great in this partnership, they allowed me to take artistic direction and introduce more variety into the collection so that the selections are truly pieces I would wear or my friends would wear.’

‘There aren’t a ton of cute swimwear brands that offer different levels of coverage and quality that Cupshe does,’ she added.

The beauty then named her favorite piece from the collection.

‘My favorite piece from our collection is definitely the zebra print swimsuit. I love how the pattern is so dimensional but also very chic and simple,’ she added.

She also told DailyMail.com that her personal style is in the collection.

‘My Cupshe collection is versatile, much like my own style,’ noted the star.

‘There are pieces that are super classic and simple; and ones that are bolder and more outgoing. There really is a suit for any type of mood you are in,’ she shared.
