An Instagram model flaunted a style from her own swimwear range with her pal.

Pauline and Mathilde Tantot own the brand Khassani Swimwear which offers a variety of sexy styles.

The stunning twins have debuted outfits from their brand before – and we think it's seriously sexy.

But now Pauline, who has 4.4 million followers on Instagram, left quite a treat on her social media account.

She wore a black baseball cap and covered her right boob with her hand while only wearing the bottom half of her bikini.

As for her friend Cynthia, she was bent over showing off a red bikini from Khassani Swimwear.
