very nicely made for Germany workwear market, "Mustang Jeans Work System" they call it, bought these second-hand in 00s, still in great condition, gentle wear and fading on front of legs and seat area, but no stains, few small holes, see pictures. 

Mustang are well established in Europe, from their base in Germany, and these dungarees are top quality in mid-weight ringspun denim.....triple stitched main seams, very nice stud buttons and metalwork on the straps, bar tack stitching to reinforce all stress points, built to last, ...nice vintage patina too as the grey has faded

strap length from waist front over shoulders to waist back  42", with another 3" length on the strap adjustment

So I am 6ft, jeans waist usual 34-35"/i/leg 30-32, these fit me perfect, with dungaree waist of 40 " and i/leg 31"   .  Would fit slightly taller, and shorter too by adjusting shoulder straps shorter.  Simple ,   and you dont want Dungarees too tight as sitting and bending becomes painful and tends to burst the side adjustment stud buttons.  

All this info is to help you get bib dungarees that fit you good. For working in, they need to be loose fit and hang from shoulder straps, with adjustments in straps and on waist side buttons

these would suit women as well as men, as the measurements allow you to see if likely to fit you...workwear dungarees tend to be unisex in the way they fit as they are looser than jeans usually

lots more being listed, mens and womens vintage denim coats and jackets, shirts and jeans, workwear dungarees, and more
