I just ordered one of the wool blend Newsboy caps like those worn by our own DR Elmore.
Mind you, I'm not trying to pass myself off as DR Elmore. I'm actually stealing borrowing this idea from Alby Potts. I think it will be perfect to wear whilst playing ACT ONE -- or anything, for that matter.
And if I end up wanting something slightly different, hats.com has plenty of good looking styles to choose from.
