569 are cool, but they're a bit too loose/baggy, especially if youre on the grown man look. 559 are cool for casual everyday s**t, but 501s>>>>>>>>. 514s are dope too if youre a skinnier dude and 559s are too loose/baggy.
the difference between 501s and 505s is the fly (button vs zip) AND most importantly, the seat of the pants is really weird. basically if you have any style sense whatsoever, youre not gonna like the way 505s fit (they fit like some grandpa jeans, all high waisted n s**t) cuz they aint low rise like 501s.
if your into 559s, look for those levis RED with the back pocket flaps
