The Arlo Cardi Button-Down Vest is a stylish and versatile piece that combines the structure of a vest with the cozy feel of a cardigan. This piece typically features a button-down front, allowing it to be easily layered over tops, dresses, or shirts. The vest design usually has a tailored, open silhouette, with or without a collar, and can be made from soft, knitted, or woven fabrics like cotton, wool, or a cozy blend.
