A sheath dress is a simple style dress designed to follow the curves of your body. It has no waist seam and can be sleeveless or with sleeves. Very flattering on most average figures when it fits perfectly. Sheath dresses can be dressed up or down and can be worn to a casual event or to a wedding or cocktail party. A black color sheath is a perfect Little Black Dress (LBD). When in doubt wear a sheath style dress. Always have the fit tweaked by your tailor if it doesn’t fit perfectly.
