With a waistcoat, yes -- I agree.

Are the following looks better? Anyone have a favourite?
I think all three look perfectly fine! I find that I like #2 just a smidge better than #1, though they're both great, and it took me a few minutes to figure out why. Seems that if due to heat, or even just being very informal, you're going to go sans necktie and with rolled sleeves, keeping the vest buttoned up seems to contradict either idea -- seems like you're "sending mixed signals": Trying to be sensitive and open, but not letting anyone get to your soft creamy center. As for wearing the belt with the open waistcoat. . .Hmm. Yes, I think it would look equally good with or without the belt.

And the short-sleeved shirt and belt, sans waistcoat, for really warm weather? Yes, I agree completely.
