Kylie Jenner Hangs Poolside in a Chic Black Thongkini With Her Baby Son

Kylie Jenner is having somewhat of a quarter-life fashion renaissance as of late, and it's even reached her swimsuit collection. The 25-year-old star took to Instagram to post a series of snaps from her autumn-ready home, including her children's matching sneakers, her pumpkin entryway setup, and a bikini snapshot in which she's seen hanging poolside.

In the first photo of the bunch, Jenner looks down at her son, lying hidden between her legs on a pool lounge chair, visible only by his feet. Her long, dark hair is pulled back, revealing a black one-shoulder thongkini. Clearly, although Jenner appears to be in fall mode, she's still enjoying that warm Southern California weather. This swim look certainly isn't Kylie's first thongkini, but this minimalist black design is ideal for these transitional periods between seasons. According to the brand's Instagram, it's a Rielli design, and Jenner has been a longtime fan of the swim label.

Jenner is back home after a whirlwind set of appearances at Paris Fashion Week. Styled in the past by Jill Jacobs, there's been no official word just yet about who, exactly, was responsible for the beauty mogul's latest string of couture ensembles. In Paris, she certainly pulled out all the sartorial stops, wearing a shaggy hot-pink dress by Balenciaga, a sheer lace cutout catsuit from Mugler, and a plunging cone-bra navy velvet Schiaparelli gown, among other high-fashion outfits.
