The OP has to be able to have separate sizes for the upper and lower body. Unfortunately, bibs are sized for both, so one area will be too small/big to the other area. He/she should find a pair of shorts that fit then go from there. I have to do that. I am 5'8" with 34" waist, 26" gauds, 44" chest and 17.5" neck. I have to wear Aerotech 36-38, maybe 38/40 shorts. The grippers on the 32-34 shorts are too small for me to get that size on. The bib shorts that fit the lower body are way too long. I top it off with an XL Aerotech jersey because I can't zip the zipper up on a L. The tail of the XL, like all bike jerseys that fit, will go below my a$$ like a tunic. The situation gets worse as I lose weight because the waist is the only area that really gets smaller. That will actually vary with how much climbing I do. If I'm doing lots of climbing, the legs will get bigger. If it's those rides on the Cap trail between Richmond and Wburg, they stay the same.

The one positive out of all of this is................I don't have to worry about wearing nice jerseys with logos! Every jersey I put on looks bad.

It's the same for any type of endurance sports clothing. Some of the upper level brands like the one you wear are not possible for me.
