Original American workwear was made from brown cotton duck before it evolved to denim. Shades of green, ochre and khaki soon followed. The original charm lives on through contrived wear at the edges of the garment body along with the original buttons and braces. Huge baggy shapes were practical in lightweight colours emulated today as a fashion feature. Zippers were not original details but have been adopted and readily accepted for stylistic embellishments.
Work style in olive drab; khaki; saddle brown are seen in flying jackets, work waistcoats and army fatigues.
Mix it up with fashion pink and soft cinnamon plus work details of crossed brace backs and patched pockets. note the "washed" finish which enhances the seam pucker making the garment look more "original" - hardly so in pink!
.... and soft green aprons worn as a fashion accessory or even a maternity take on work style.
