The struggle: It’s a face-melting 95 degrees outside and a center-of-the-Arctic 55 degrees in your office.

Rather than initiating World War III with Gary from maintenance, consider keeping a lightweight sweater permanently at your desk.

Let’s see which styles are the most versatile.

The No-Brainer Cardigan

A button-front, slightly slouchy cardi adds warmth without bulk. Styling tip: Don’t wear it the traditional way. Drape it over your shoulders for an updated look.

Zara ($30)

The Long, Modern Cardigan

Lightweight, breathable wool (yes, you heard us: wool!) makes an extra-long duster the closest thing to wearing an actual bathrobe--but in a chic way. Scrunch up the sleeves to show a little skin.

Mango ($80)

The Oversized Pullover

Nothing says comfy like a giant V-neck, but to keep it office-appropriate, look for neutral hues and a pretty, feminine shape. You’ll still want your shift dresses, pencil skirts and tapered trousers to peek out beneath.

DKNY ($195)

The Dolman Tunic

Similar to the traditional pullover, an open-weave tunic gives off a slight Boho vibe but can still top some of your more casual business looks.

Anthropologie ($228)

The Breton Stripe

Lovers of prep: The classic nautical knit also works in the office--but only in sparing instances, like with a crisp collared shirt underneath.

Vince ($379)

The Flowy Kimono

OK, technically not a sweater. But if your office is more laid-back (and less frigid), layer up with a breezy printed cover-up. It looks especially polished over head-to-toe neutral ensembles. (Think: white blouses with white jeans.)

Topshop ($70)
