There are a few things about Levis 501s that make them special. First of all, consistency. Yes, the fit of them has evolved over time, but they are basically the same pair of jeans that you could have bought 50 years ago. Second, the button fly. I just dont like the feel and look of a pair of jeans without a button fly. It seems to make the fly area softer, if that makes any sense, and lie better, at least for me. Thirdly, someone had commented about the "washes" of the jeans not being very interesting. Thats kind of the point of 501s. People above a certain age, and even some who arent (im 31), actually look for jeans that dont have "special washes" . We like jeans to look like jeans. Which generally means a variety of blue (perhaps black, but I dont own any myself). No silly "whiskers" or heavy distressed areas. 501's come in a variety of colors, but whats nice is they have avoided some trendy details that you find on all the designer jeans these days. I guess what I am saying is its comforting to be able to walk into a Levis store, grab a pair of 34 waist, 32 inseam (in my case) 501s and walk out of the store and know they are gonna fit and that I will be happy with them. Concerning the actual fit, thats like anything else. Its totally subjective. Someone mentioned them fitting terribly on the thighs. For every person like that, there is someone else who loves the way they fit. Obviously one pair of jeans isnt going to fit every body out there. And lastly, along the sames lines, I like how they are impervious to changing trends and styles. Look at some pics from the 1970s. You see plenty of silly jeans. Flared legs, funky pockets etc. The guy who wore those probably thought he was really stylin' at the time. Ten years later he probably wanted to burn that picture. Same guy in a pair of 501s in that pic from the 70s looks just fine 10 or 20 or 30 years later. Perhaps the guy today wearing todays version of the silly trendy jean will want to burn his pic 10 years from now, who knows.
