To choose the best sheath wedding dress, carefully consider fit as well as style and color. Sheath style gowns should neither be too loose nor too tight. Rather, they should skim the body to create an elegant effect. If your body type isn’t naturally tall or thin, you should look for slenderizing lines in the dress. The fabric should drape on your body attractively. Lace tends to work especially well for a sheath wedding dress, but any medium weight, sophisticated bridal fabric can usually function in this kind of gown.
