We have a pair of girls retro shorts size 10 vintage item.  The fabric is similar to a lightweight denim.  They measure about 22" around the waist with the elastic un stretched - I would say it would stretch comfortably to about 24".  The waist to crotch is about 11 1/2"  and the side seam from waist to lower hem is about 12" on the side.  The widest point on the hips is about 30".  There are a few stains on the top front waist - the worst one shown in my photo.  It is about 1" x 1 1/4" in size.  The other I just spotted now and is on the opposite side of front waist band is a faint gray circle about 3/4" across the center.   They show some light wear.
