Because of its smooth, shiny finish, satin tends to highlight lines and textures underneath. To achieve a flawless look, seamless underwear in nude tones is a must. Invisible slips or shapewear help create a smooth silhouette without visible lines. For bras, opt for styles without lace or bulky seams to avoid showing through. A fine stretch slip worn underneath not only prevents marks but also enhances the fluid drape of the satin. With the right foundation, your satin dress will always look polished and elegant.
