I have always rode in jeans. Breeches are weird.
Now, I'm cheap so I refuse to spend more then $20 (and YES, a $2000 saddle for horse is DIFFERENT) on a pair of jeans. I go to Stitches, and I am just now getting to the point where I'm replacing my high school jeans - the last good pair I had the ambulance guys cut off me, the inconsiderate jerks.
I HATE clothes shopping. But for the price of them, they have done well. Maybe if I go next month, I won't have to go for another nine years.
