Basking in some rare UK sunshine, Julia Roberts' recent Instagram post featured her wearing a luxury athleisure ensemble by British designer Wales Boner. A first-class combination, the star looked relaxed and elegant in a navy zip-up tracksuit top with matching sporty wide-leg trousers as she soaked up some rays on a hotel rooftop.
Pairing the navy two-piece with some brown ballet flats from the celebrity-loved, Quiet Luxury brand, The Row. We couldn't help but think about how comfortable the star looked, and how this dressed-down two-piece was the perfect summer look for those looking for chic but cosy airport outfits. A great option for what to wear on a plane, Julia Roberts' was seen legs up on a chair, laidback in her stylish but unfussy set.
