L.A. based-brand Doen has released some gorgeous chunky cardigans that are perfect for fall. This women-owned brand is constantly rolling out new pieces that everyone wants to get their hands on. Some of my winter favorites include this Bernadette sweater or this Cardiff cardigan.
J.Crew also has some chunky cardigans as part of their Point Sur collection. Wait for one of their sales and you can scoop up this one like I did for around $50. I have both the green and caramel colors.
Another favorite is this wool-blend H&M cardigan - perfect over dresses or with jeans for cooler weather.
