I also wear suspenders & belt while hunting.
The suspenders are the Perry type; they attach to the belt by a notch or whatever that actually slips behind the belt and grabs it by the bottom. Most stores that sell hunting clothes have 'em.
Not exactly a fashion statement, but they work very well for hunting and aren't un-comfy at all.
Like Joaquin, I like my hunting pants a tad loose to leave room for longies and for air circulation. I generally wear cordura-faced brush pants while bird hunting.

MGE:
Like you I also wear cordura reinforced pants for bird hunting, wich is not usually in such cold weather as with deer hunting.
I only wear wool for deer hunting wich starts in Pennsylvania the first monday after Thanksgiving day.

For a moment I thought you mean corduroy, but cordura nylon makes more sense...
