Keenan is the type of brilliant, season-defying sweater you’ll reach for constantly. It’s knit from high-twist Italian cashmere that’s incredibly soft on skin—meaning you can skip the base layer completely—with a close fit that tucks smoothly into anything high-waisted. Its most defining feature, though, would have to be those goop-signature puff sleeves: A small sliver of padding helps them hold their shape, while the preppy striped cuffs keep things in place.
