It depends on the purpose and what kind you like. A messy job, I like a full bib apron. I posted a picture of mine made from a man's extra large black shirt. I didn't put pockets on it but it would be easy to do. If you put aprons into the QB search some should come up. Mine made from a man's shirt was a youtube video so you might check youtube too.
For cleaner jobs with pockets for money, I like a waist apron. I have made the waist aprons out of a rectangle of heavy duty fabric (denim works well) folded up, sewn into sections and add a waist band.
