From Merchant & Mills.
A traditional unisex apron for industrious demands. Choose oilskin or denim for a classic workwear feel, or a soft tumbled linen for wearing everyday around the house. The workaday has 3 pockets, and a waist and neck tie that can be lengthened or shortened as needed.

Suggested fabrics – Cotton canvas and twill, denim, dry oilskin, oilskin, medium – heavy weight linen. You can make the ties in self fabric or 25mm webbing or tape. 

See Marcy's version in denim below - topstitched in acid yellow green, using a sharp topstitching needle, two threads in the needle, a long stitch and the 'stretch' stitch (2 stitches back, one forward). I made the bib and width wider for more coverage.
LOVE it!
