For comfortable jeans the Lee Extreme Motion ones are great. I started buying them after I started lifting weights and grew my thighs and ass a little bit. They look reasonably professional for work, fit really well, but don't last all that long.
I have switched a lot of my pants and shorts over to Outliers. They are pricey but last really well, the first pair I bought a couple years ago still look like new. The Slim Dungarees and the Bomb Dungarees are my favorite. I bought my first couple pairs through their "WTF" sales (2nds and returns sold blind at deep discounts, kind of like when Busse does grab bags) to see if the sizing worked and once I found it did I started buying them off eBay or Reddit.
