So, I have successfully reduced my waist from size 38 to 34, but I am confronted with an unanticipated problem. Because I do a lot of biking (often >3hrs/day), my thighs (quadriceps muscles) have grown quite considerably. I am no body builder and classify this as a mild nuisance rather than an accomplishment, but that is how it is, and I have to take it as it comes.

So, I have ordered a few new 34-by-34 chinos from Zalando. Waist and length are fine, but they are all very, very narrow at thigh level! It's not that I cannot wear them, but it is quite at the limit of what's tolerable. My question to you: where do I find (preferably online) chino trousers ("business casual") with a biker-compatible thigh cut? I should also say that I am the least fashion-conscious person in the entire known universe...
