Never used it.  But I like the "sand" and "cinnamon" colors, though those names are 'orrible.

I dont see any problem with the navy cotton suit, except that it probably hides sweat and other stains a bit more. Tan is not that smart a choice for the working man in our dirtiest cities. Thus, it depends on why you are choosing the suit. If it is for a lawn party, you might want tan but for work a medium colored olive or navy may be better.

Wool/linen blends may be a better pick than cotton- the pic'd cloths all look like various shades of green on my monitor.

The lapels on mine are nicer! I believe in this scene Austin Powers is telling his adversary: "I don't speak frickin' Dutch."

Jokes aside, I have a tan light-weight wool suit that, IMO, serves better than the cotton variety.  Unless one is looking for the casual, relaxed/almost faded summer look, then cotton offers a better choice.   Wool fabric, though, gives the suit that least bit more if used during the work week.  Without fail, I always get compliments when wearing my tan suit - not what I ever expected.  I think the color is right for the season, but the fabric gives it a polish most people don't see with the typical poplin.
