Sleep black garter belt from the 90s. Buckles round the hips/waist with four garters all round. Length of garters is adjustable Its not an elastic but the fabric does have some mild give to it, perhaps a thick nylon, or something with elastic in it? There is no label but there is a tiny tag that says 42, so I imagine thats the size. Measurements below though.
Excellent vintage condition. No issues to report.
Waist: 36″ to 42″
Garters: 11″ to 21″ and they have stretch as well.
