I'm a reasonably big guy (40" waist, 5'10"), and the XLs fit great.  Not good but great.  I actually used these as a part of a Jedi costume.  The color is right on, and the right hip pocket is deep enough that a smart phone will be in far enough that it won't fall out if you sit down.  Very, very pleased.

This is probably not what the usual scrub-market cares about, but I am not one who usually wears scrubs and was so pleased at the excellent fit.
