barbed pin stripes 

100% cotton

made in usa(?) circa 1991

used

size M? (waist measures 37cm unstretched, 51cm stretched to max, 100cm waist to cuff)

very good used condition. have seen significant wear however were well-loved. the waist is a little blown out however the elastic still has stretch plus drawstring is included. the top of the waist is fraying but otherwise flawless. no tags present & my guess is they were a medium & fit waist 32-36"
