Hailey Bieber and Kendall Jenner wear thong bikini on vacation

Most of us know the difficulty of trying to plan a vacation with friends but never successfully removing them from a group chat. However, Kendall Jenner and Hailey Bieber actually celebrated New Year's 2024.

To usher in a new era, fashion's most stylish best friends gather in Barbados for a luxurious beach vacation. There, the two coordinated their sartorial energy in a variety of summer swimwear — namely: thong bikinis.

Hailey's New Year's Eve bikini

Bieber recently returned from a trip to Aspen where she traded in her fur coat and Sugar Plum Fairy makeup for a sheer cover-up, her strawberry girl summer aesthetic, and, most notably, a cheeky two-piece.

The Rhode Skin founder showed off every possible angle of her playful swimsuit (which is still on sale at Miaou) as she posed on a yacht. She wore a forrest green triangular halter top with neon yellow straps. If you're wondering about her lip combo, Bieber left a clue under the straps of her bottoms: Strawberry Glazed Rhodes Skin Peptide Lip Serum.

She completed the look with a matching thong, which she showed off in another photo on Instagram from Barbados. To spice up her beach look, Bieber added a straw bucket hat, black sunglasses, chunky gold hoops and a chic body chain, one of her favorite beach accessories.

Miraculously, Hailey's Miaou set is still available for purchase online. Each piece sells for $80 individually, or $140 for the complete set.

Kendall's equally cheeky look

Jenner posted a nearly identical photo showing off her own thong bikini. In stark contrast to Bieber's tracksuit, hers was a knitted string design covered in red and white stripes.

Bieber also shared the pinnacle of her elegant evening wear, starting with a chic floor-length white low-cut dress.

The model wore a white vest from ÉTERNE and a low-waist metal mesh medium-length skirt from Christopher Esber, continuing the cool girl style under the sun. The combination gives Bieber an undeniable "mermaid on land" type vibe.
