Welcome back to Dopamine Dressing Season! With the sun setting at 6 p.m. and the clocks falling back next week, now's the time to fill your winter wardrobe with color-forward fashion. Take it from Hailey Bieber: Trading your tired black coat for a cobalt blue coat can bring some liveliness to the season's shorter days and limited sunlight.
Sure, 70-degree days are still the standard in Beverly Hills, but that didn't stop Bieber from layering up. She stacked a knee-sweeping trench coat—in the most striking shade of blue—over a black crop top, matching trousers, and the prettiest patent leather slippers. Don't miss the croc, burgundy Chanel Flap Bag beneath the coat's cerulean-adjacent collar.
Color aside, the outerwear featured the same slightly oversized silhouette as the more minimalist pieces on her coat rack. In addition to proving unmissable on the street style circuit, the hero pigment was also a favorite on Fall/Winter 2026 Fashion Week runways.

And the trend's takeover is nowhere near over. Just as Marie Claire claimed last March, everything is still coming up cobalt. Months after Dua Lipa, Kendall Jenner, Jennifer Lawrence, and Jessie Buckley declared cobalt the color of 2026, Spring 2027 fashion shows guaranteed it isn't going anywhere.
Everyone from Chanel and Calvin Klein to Proenza Schouler and Loewe covered their collections in blinding blue looks. Better yet, French girls at Paris Fashion Week followed suit outside the shows. Parisian trendsetters couldn't stop styling cobalt blue with trending tints of red, including tomato, raspberry, and poppy.




Playing with colorful coats has always been a Hailey Bieber Hobby. Back in the day, she sampled burgundy, croc caramel, and even neon green trenches. But blue is new for her. If the color trend appeals to you, too, shop the cobalt blue coats below. Trust: They'll brighten up even the gloomiest winter day.
