Vintage Jordache side slit shorts NWT

Sizing is a little confusing on these , these shorts are vintage but the tag looks like teenagers , however these are a 30” waist . Size 11/12 . Girls 11/12 are a smaller waist size , womens 11/12 are a 30 “ waist . These shorts are UNWASHED. . I would assume they will shrink after first wash and dry . Measurements are Waist 15” flat front. . Rise 10-1/2” measured to TOP of waistband . Rise 3-1/2” Side slit is 1” Hip 19-1/2” flat front . . 100% cotton . No matter what the tag says , I remember the shrinkage . Made in Morocco ., and Bright Red !!
