Whatever fits best.
I fit into Ring Jacket.
They are a pair of Made in Japan Uniqlo Selvedge Denims.
I had tried to buy them at a late stage and they were all sold out in Hong Kong and Singapore. I found them in a Uniqlo in London.
The other pair I wear regularly are a pair of square cut Levi’s bought in Hong Kong. I have a secret 3rd pair in hiding that I will start wearing after I burn out my Uniqlo’s!
I think the most it sold was when it was going out of business :(
