Straight-Leg Horse Riding Jeans - Black

I take a regular 33 waist. I am a regularly shaped man. The 34" waist came up something like a 28" waist. The trousers might be fine, returns are free and my postage was refunded but I suspect I'd have to go 38" waist to get these to fit. They look like thin denim breeches with an underboot strap. A good design, hopelessly buggered up with sizing. I don't like prancing about in breeches so something looking more like regular trousers was really attractive to me but I guess I'll be wearing breeches a while yet. I note sizing complaints go back a long way. I'd have thought Decathlon might have dealt with it by now.

I'm a 36" waist, as per the reviews I have tried larger size both the 38 and the 40. They were both extremely tight on the thighs and only just fired the waist. No way i could have ridden in them. Altough they we labeled as different size I'm not at all convinced they were different (couldn't compare as order 38 first then returned for the 40). Really annoying as the seemed well made. I have brought walking trousers from decathlon at 36 waist and they fitted fine so very disappointed in these

Tried on my new riding jeans that are supposed to be 30" inch waist..
They are TINY! More like 26"!
Now I'm guessing I have to pay to return them
