"Transitional jackets" are the Goldilocks of outerwear—they're neither too heavy nor too light, but just right . They hit the sweet spot of being insulated enough to act as a buffer against crisp autumnal breezes without the risk of overheating. But among the usual suspects (denim jackets, motos, bombers , cargos, and so on), the surprise sleeper of the season is the duster, a lightweight coat that's similar to a trench in weight, but longer in length and more fluid in shape.
And we get why the celebrities are into it. The shin-grazing topper has all the qualities of a robe (but one that you can wear out in public, obviously)—it's comfortable, it envelops you like a hug, and it flutters behind you every step. So it makes sense that the stars have been wearing theirs everywhere, from flights to a night out to the red carpet. To get the exact look, we performed our magic, identified eight celebrity outfits, and located where to buy them. You're welcome.
