Hailey Bieber’s wraparound sunglasses
The whole outfit was a sweatshirt and flip-flops. The sunglasses are what stopped it reading as giving up.
Wearing: Out for lunch in New York — Wraparound sunglasses with a sweatshirt, stovepipe jeans and flip-flops
Hailey Bieber went to lunch in an NYC sweatshirt, stovepipe jeans, flip-flops and a plain black shoulder bag. Vittoria Ceretti was photographed the same day in a grey zip-up hoodie, baggy jeans, a red T-shirt and flip flops. Both were wearing wraparound sunglasses, and in both cases that is the only element of the outfit doing any work at all.
This is the most practically useful thing in celebrity dressing and it gets written about the least. The clothes are deliberately anti-style — the point is that they are not trying — and a single hard, modern accessory converts "not trying" into "off duty". Those read completely differently, and the difference is one object.
A wraparound does it better than most frames because the shape is unambiguous. It has a continuous curved lens and no soft edges, so it cannot be mistaken for a default choice the way an aviator or a plain oval can. It looks selected. Against soft, shapeless clothing that contrast is the entire mechanism.
Worth being straight about the fit constraint, though: a wraparound sits close to the face and follows the curve of the skull, so it suits a narrower face and fights a wide one. Frame width at the temples is the measurement to check, and it is the one thing a photograph of somebody else will never tell you.
What transfers
When an outfit is deliberately plain, one hard-edged accessory does more than three soft ones. The mechanism is contrast: soft clothes plus a single sharp object reads as a decision, while soft clothes plus soft accessories reads as a laundry day. This is the cheapest styling upgrade there is, because it needs one item and not a wardrobe.
