Since your office climate is pretty much static during the summer (read: permanently freezing), you'll need a cardigan that'll go with absolutely everything you own without attracting too much attention. What that means? A black or gray cardigan that hits you at mid-tush in a weave that won't pill, won't pull, and is thick enough where it won't show every tuck and fold of your shirt. In this case, cashmere is really our go-to, and this cardigan from Tory Burch is basically completely neutral in terms of style…a good thing, in this case.
Tory Burch Miranda Cardigan, $295, available at Tory Burch.
