Im thinking about buying a pair of 1947 501xx's and was wondering, does the advice to go up two sizes in the waist still hold true or is it better to now only go up one size in the waist instead? I don't want to look through this entire thread for the answer. Thanks guys for all your help. So you want to spend a lot of money on a pair of jeans that you are going to use for a long time, but you are too lazy to read back a couple of pages or at least press the search button? Makes me want to help you even more. You should try downsizing by 3 or 4 sizes like you do on your APC's..
