While the President has had an impressive year in style (his opinions on the current state of menswear notwithstanding), it's clear that First Lady Michelle Obama sits on the throne of most stylish person in the White House. One of the best-dressed moms ever, her wardrobe consists of pieces from lauded designers like Tracy Reese and Thakoon, easy-wearing garments from J. Crew, and menswear heavyweights like Thom Browne. Talk about variety. She's established a pretty good uniform though—cardigans with just about everything. It's a good thing the versatile knitwear piece can be worn in a bunch of ways. While you won't be wearing it with a dress or skirt, you certainly can put it on over a T-shirt and jeans or switch it up as a layer under a sportcoat.
Cardigans are appropriate for any occasion.
