I'm looking at dockers and trying to figure out which fit is best for me. I've tried on D3 in the past and it just has too much room. I'm a reasonably thin/average guy with a very small pot belly that's not noticeable, I'm 5'8 at 165lbs. I'm scared to try the D1 and Alpha collection because I don't want it too look very tight on me, I want there to be some space in the legs and seat but not like sloppy baggy pants if you know what I mean. Any suggestions?
