The past few seasons have seen a surge of curated streetwear styles, aimed to appear more casual, sleek, and understated than that of their couture converse. From running errands to being a “Pilates Princess,” everyday activities have become grounds for Instagram-worthy attire.

Coined “off-duty” by followers of fashion, the athleisure trend reflects our desire to be subtly chic, no matter the occasion. A gym outfit, when styled with intention, can give high-fashion credibility to the wearer, despite its comfort and functionality — factors often associated with a different sector of the retail market.

A Sporty Spotting

If you’re looking for inspo to elevate your own athleisure attire, look no further than our favorite it-girl, Hailey Bieber. The Rhode founder was recently spotted making her way to a workout class in Los Angeles wearing FORM Activewear’s viral Criss Cross Bra, paired back to a classic, all-black co-ord set.

The activewear label is known for its buttery fabric, form-fitting silhouettes, and endless styling opportunities. Bieber showed off her set by layering her sports bra underneath a sheer, off-the-shoulder top with hot shorts. The trendsetter playfully accessorized the sporty style with her signature black sunglasses, mid-sized gold hoop earrings, and a thick white headband.

Bieber showed support for her husband’s newly-launched clothing brand, SKYLRK, by strutting in a pair of the brand’s platform, sculptural slides. The ultra-modern design by Justin Bieber fuses contemporary silhouettes with casual comfort, resulting in a pair of kicks that are ideal for pre- and post-Pilates, and, of course, off-duty model obligations.
