When visiting a frosty city like Aspen, you need to dress warmly. Clearly, Aubrey Plaza knows this, which is why she recently stepped out in the wintry destination wearing the softest, chicest cashmere stockings we've seen this season. According to the brand Calzedonia, Plaza kept the chill at bay in Aspen thanks to its cult-favorite Opaque Matte Cashmere and Modal Tights. With temperatures dropping to -2 degrees Fahrenheit, these nylons played an important functional role in the actress' look, which included a pleated plaid mini skirt, fuzzy sherpa jacket and lace-up suede boots.
