It varies but I am usually around a 16 to an 18. I do have a 32 and 34 in some other riding pants. But I can't find a sizing chart for the particular riding breeches I want to buy. I have an Ovation Pair that I really like but its an XL and because of my weight its to small. So I am thinking a 34 would be big enough.Might I ask what size of pants you wear now?
