When I scheduled a few big meetings in New York, I bought this Theory Sheath Dress as a staple I could carry from my meetings to happy hour with friends with only the change of a blazer and a necklace. And although I was a little nervous about spending so much on such a small dress, I am so happy I did. It has a slimming fit, is sexy yet sophisticated, and looks just right with a tailored blazer, pearls, and sky-high heels. It’s pieces like this you will keep forever, all your friends will borrow, and your daughter can wear, because they are simple and timeless. I know I will wear this in the winter with solid or patterned tights and a fitted trench. Easy and effortless.
