You know how it goes. They say one thing; they mean another.

Generous Colleague offers to cover for you — so she can kiss up to the boss. Doting Boy insists on walking you home — so he can invite himself up. Tactless Mom suggests you settle down already (or freeze your eggs) — so she can get a grandchild.

Former Heatherette and Betsey Johnson technical designer Laura Seymour offers a new line of cozy, easy, slouchy dress up clothes that makes you look good — without even trying.

Imagine: You, in a long, chunky sweater and vest with matching knit leggings, looking like you’re ahead of the fashion curve. Imagine: You, in a pleated shirt-dress, looking like a well-planned idea (even if it was an afterthought).

You’ll want to wear her raglan cap-sleeve tees to the office, the bar, and straight to bed. Most everything in the collection comes in neutral color palettes, to inspire maximum mix and match.

And, in this case, we really mean it.

Available at Castor & Pollux, 238 West 10th Street, between Hudson and Bleecker Streets (212-645-6572). To see styles, go to lauraseymour.net.
