“I just started back in an office job in New England, where winters demand something more substantial than a hip blouse,” writes a reader named Melissa. “But thick sweaters tend to look too relaxed for an office. I’m looking for warm, comfortable, cozy sweaters that can translate to a more formal office setting. Women’s dressier sweaters tend to be thin (even in cashmere) and not as warm as something you’d break out on the weekend. But I’m freezing and need something to keep me warm at work. Can you take this challenge on?” Happy to, Melissa, and I have to say that while I never thought about it before Melissa raised it, it is almost invariably true that the warmer, more comfortable, and cozier a sweater is, the more casual it tends to skew. There are a few chunky knits below that do manage to be office-appropriate, but my primary advice here would be to get some scoopneck Heattech T-shirts from Uniqlo, and layer up. I think this shrug looks completely toasty and very office-appropriate.
