Sweaters are cozy and warm, and the great thing is you just toss one on and your done. No tucking, buttoning, adjusting necessary. But making a comfy knit look a million times more polished for the office is as simple as tucking it in. Depending on the length and weight, you can tuck it all the way in, or just do the half tuck for bulkier knits. Either way, it’s just like tucking in your shirt, it instantly makes your outfit look 100 percent more put-together.
