Having recently gotten a shipment in from Levi's (since Macy's doesn't carry the 513's in store in my area), I have to say, these are my new favorite jeans. As a tall and slim guy (6 ft. and 160) the 514's are great, but can often feel too loose/baggy for my taste. I also have some 511's but I wear those in more casual settings than anything else. The 513's are probably the best fitting jeans I've ever gotten, outside of the GAP straight fit.
I know the 514's have popularity in the Dappered Community, so I want this thread to serve as both informational (for those who are looking for the best fitting jeans out there) and to see what others think/how they compare the 513's to the 514's.
