I like traditional style, trim fit, and a great feel in jeans.  The best fitting Levi's are 501 shrink to fit button fly in rigid or black or 511 rigid dragon.  These jeans give me the look I like and want in a pair of jeans.  Levi's are the best! I would not trade them for all the designer and other brands of jeans that have ever been available.  An individual must know what size must be purchased to give a desired fit.  For some reason other Levi's styles fit differently even though they are the same family group like 511.  These white jeans have too much crotch.  In more recent times Levi's seem to be making jeans for heavy set boys.  I want a trim skin tight fit.  I am able to wear a size 28" waist in these white jeans.  It they would fit like they should a 31" waist should be just right.  From the mid thigh to the waist 511s fit better than 510s.  I would think they would be the same.  My goal was to purchase a white jean that would be trim fitting everywhere so I could have some insulation in cold water while swimming.
