The robe is only offered in two sizes, S/M and L/XL.  The L/XL fits me alright, could be just a little bigger.  At 5'10" and 230 lbs, I'm not small, but I'm nowhere near huge, either.  I wear a 36 in pants, and would likely not want to wear this robe if it were any smaller.

It's a nice lightweight robe, but the belt comes out of the dryer folded up like a cord.  You can't straighten it out unless you want to wet it again and lay it out flat to dry, or iron it.  Something of a pet peeve of mine.  Surely there's some facing type material that would help alleviate that, but that's a detail Nautica did not bother with.

I also forgot how much shawl collars annoy me.  The robe I replaced was a medium weight knit jersey that draped very well and had no collar.  It was largely effortless to put on, as a robe should be, in my opinion.  The shawl collar on this is a bit of a nuisance, trying to get it folded and settled neatly.  You should not have to check a mirror to put your bathrobe on.
