Well, I think ethandesu looks great wearing trousers with a higher rise sans jacket (and with pleats, even!), so perhaps they’d look great on you, too. 

It’s funny, I’ve actually been discussing this topic somewhat with dieworkwear, who is on a bit of a crusade to find the perfect pair for himself. 

As far as where to look, I’d start by trying on multiple pairs from Brooks Brothers (in their various cuts, avoiding the low-rise cuts like Milano and Regent), Polo Ralph Lauren (perhaps with the Preston cut) and even giving Lands’ End a shot on the more affordable end. 

It’s worth noting though that you’ll probably want to get these to a tailor and altered to taper better to your frame. I also wouldn’t go too extreme in the taper, either. You’ll probably want a bit of break in them and a wider leg opening (probably 8” or more) to accommodate.
