Although I am more a Levi's guy, I occasionally wear Wranglers if I am going for that western look. Regular fit Wranglers are a good choice for men with medium to large rumps, whereas the slim fit ones are good for those of us with more compact rears. Slim fit Wranglers are tight (much tighter than Levis), and they do make an an eye-popping crotch on a well-hung man. So, depending on just how eye-popping you want to be, you may consider upsizing a bit. For instance, I have a 29"x34" pair of slim fit Wranglers, which leave very little to the imagination, and also a 30"x34" pair, which are some tamer in respect to the bulge factor. Wranglers also fit a little longer than Levi's. I can wear a 34" inseam in Levi's with regular shoes, but a 34" inseam in Wranglers is for wearing boots only.
