NWOT (sourced from a boutique going out of business) I have a crop top in my closet that matches these biker shorts perfectly! I give discounts if you purchase them as a set (find the listing that says Nikibiki set and select Vintage Chocolate). Size: One Size. Seamless biker shorts with a form-fitting silhouette and vintage ribbed detailing. Fabric: 92% Nylon / 8% Spandex. Made in the USA These biker shorts are knitted with elastic waistbands for a secure hold and a comfortable fit.
