How Hailey Bieber’s 2021 Pilates Outfits Rewrote the Celebrity Shoe Blueprint

Throughout 2021, Hailey Bieber developed a recognizable post-workout wardrobe built around coordinated activewear, oversized layers, padded slides, and collectible sneakers.

Frequently photographed arriving at or leaving Pilates sessions in Los Angeles, she helped popularize the polished athleisure aesthetic that defined celebrity street style during the early 2020s.

From monochrome black separates paired with Gia Borghini sandals to tonal olive ensembles and colorful Nike Dunks, these outfits illustrate how Bieber helped shape a wellness-inspired approach to dressing that resonated far beyond the gym.

Hailey Bieber Elevates Black Pilates Staples With Gia Borghini Perni Sandals

On October 5, 2021, Hailey Bieber stepped out after a Pilates session in Los Angeles wearing one of the athleisure formulas that became central to her off-duty wardrobe: streamlined activewear finished with elevated accessories and fashion-focused footwear.

Her outfit combined black leggings, a matching cropped top, and a leather bomber jacket, while Gia Borghini sandals reinforced the luxury-slides trend that dominated celebrity street style in the early 2020s.

White tube socks and Gia Borghini’s “Perni” sandals grounded the monochromatic outfit. Defined by padded double straps and flat rubber soles, the slides reflected the growing popularity of luxury comfort footwear during the period.

Throughout 2021, padded slides became a recurring element of Bieber’s post-workout wardrobe. This look showed how luxury comfort footwear could transform straightforward activewear into an outfit that felt considered, cohesive, and unmistakably Los Angeles.

Saint Laurent sunglasses added a discreet finishing touch, while GIABORGHINI’s padded double-strap slides reinforced the relaxed yet fashion-conscious mood of the outfit.

Originally launched under the Gia Couture name, the Italian label later rebranded as GIABORGHINI to emphasize founder Barbara Borghini’s family heritage and establish a clearer identity within the contemporary luxury footwear market.

Defined by smooth padded leather straps, open toes, and flat rubber soles, the slides anticipated the comfort-driven aesthetic that would become a signature of the house.

The rebranding coincided with the brand’s growing international profile and high-profile collaborations with figures such as Pernille Teisbaek and Rosie Huntington-Whiteley, helping position GIABORGHINI among the most recognizable contemporary Italian footwear labels.

As of July 2026, Farfetch continues to stock several variations on the brand’s padded-slide formula, including the Gia touch-strap slides, padded-strap open-toe slides, crossover-strap slides, and the GIABORGHINI x Pernille Teisbaek double-strap slides, with many styles discounted from their original retail prices.

Originally introduced in 2001, the Nike Dunk Low “Brazil” returned on May 21, 2020, and again on February 2, 2024. The silhouette combines a Varsity Maize leather base with Pine Green overlays and white detailing, drawing inspiration from Brazil’s national colors.

The sneaker debuted in May 2020 with a $100 retail price and returned during the 2024 restock at $115. Secondary-market demand has remained relatively strong. StockX sales for a CM 31 pair recorded transactions ranging from $125 to $295 between late 2024 and July 2026, with many sales clustering around $180–$220.

As of July 2026, the Dunk Low Brazil continues to trade above its original retail price, underscoring the enduring appeal of early-2000s Dunk colorways among collectors and casual wearers alike. Before buying used Nikes, make sure you know how to spot fake ones!
