I went with a Redkap coverall for my jumpsuit. It was inexpensive, and only had 4 pocket (2 front, 2 rear) to remove. The size is a L and Redkap lets you pick your chest, waist, length, etc. So I went with my biz suit size. It was really spot on, but the crotch was a little high and uncomfortable when I walked. So, I ripped the crotch seams out, and lowered it a bit. It sounds horrible, but was really nothing to do. If I can, you can!
Since then I found some faux suede and elastic at a fabric store for $10.
