The jeans with the most pocket room is likely Gloria Vanderbilt. The fit nice, they’re higher in the waist, have deep pockets, and little embellishment of your trying to go stealth. Also come in just about any color you can think of. As others have said, try on some to find just the right size. Each brand fits a little differently. Most brands I fit a 14, some more like 16 or 18. I have one pair of 13.
I don’t generally wear men’s jeans anymore unless there’s a reason to. Like heavy work, since I don’t want to ruin any of my nice ladies jeans.
