Former model and musician, designer Anine Bing launched her namesake label in 2012 off the back of her own wildly successful style blog. Focusing on fit and quality, the label has become a need to know name for the fashion pack, coveted for its easy-to-wear pieces that embody off-duty cool. When it comes to its sweats, this translates to a selection of slouchy sweatshirts and sleek trackpants that are casualwear staples. Think Breton-stripe sweaters and bold slogan sweats, as well as sweatpants in monochrome. Infused with the Californian vibe, these are modern must-haves.
