Sash

[A] long, wide piece of fabric worn around either the waist or the hips. Sashes made of luxurious fabrics were used on the waists of ball gowns during the 19th century. (Encyclopaedia Of Fashion, Sash)

A long, wide piece of soft material, in the form of a band or scarf, bound around the waist, hips or slung across the torso and the ends generally tied. Sashes tied on the hip and crossing the body from the shoulder were fashionable wear for men in the later sixteenth and early seventeenth centuries. Men wore a broad waist sash in the first half of the seventeenth century and lower, to encircle the hips, on top of the justaucorps in the second half of the century. Sashes were intermittently fashionable on women’s dresses, marking the waist or hips, from the nineteenth century onwards. (Encyclopedia Of World Costume, Sash)
