Classic utility workwear dungarees, given that 80s spin by Jinglers with stonewashed denim and metal studs around pockets and straps.
As you'd expect from this style of dungaree, there's an overabundance of pockets for all your tools, pens and gubbins- I'm pretty sure you could stash the entire contents of a bag in these bad boys!

Labelled a 38, these will fit a womens UK size 16 (Bust=40 inches (102 cm) Waist=33 inches (82 cm) Hips=42 inches (109 cm), or a guy's size Small.
