Lace trim is a decorative edging of openwork fabric, patterned with holes and motifs, used to finish hems, necklines, straps and sleeves. Made by hand or machine from threads of cotton, silk or synthetic fibres, lace adds delicacy and texture to a garment. Designers often contrast black lace trim against metallic or pastel fabrics, letting the border frame skin and silhouette with vintage softness.
