Invisible-Line® Shaping Brief Panties invisible under clothing thanks to seamless, modern edge technology INVISIBLE-LINE®. Made of a delicate, breathable material, they perfectly match the silhouette. Special slimming areas emphasize the waist, flatten the abdomen, model the hips and lift the buttocks. For the hygiene of women, a cotton insert has been sewn. Figs will remain invisible even under adjacent clothing.
