I wear a 28 in ariats too, but in tailored sportsman it depends on the style. I have two pairs that are the trophy hunters I believe, they are ment to fit looser, have less stretch to them, and they come up much higher around my waist so I wear a smaller size in those, but I had a few pairs of the tailored sportsman TS breeches and I was a 30, probably could have worn a 32 comfortably as well. I know the TS style are on sale at dover and they come in every color imaginable. Grand Prix breeches fit similar to ariats as well. I just got a pair of the ariat heritage euro seat breeches and i love them. They are only 90 bucks too.
