Sheath dresses should be a staple in every woman’s closet. Simple and elegant, they’re great go-to dresses for everything from work to church to cocktail parties. Fortunately, there are beautiful buys at every price point, and you don’t have to spend a fortune to look stunning.

The two dresses above (one from St. John and one from Tahari) are both gorgeous, but one costs $98 and the other costs $995–more than ten times more! (And they’re both from the same store!) Can you tell the difference?
