In the interest of sartorial science, I bought a pair of Oliver Brown moleskin trousers. The fabric and manufactuire are both excellent.
But the sizing is generous, to say the least. I usually wear 30" trousers (so Peter Christian is out because they start at 32"). The size 30 Oliver Browns are quite a relaxed fit at the waist, with room for roast pheasant and trimmings, an extra helping of Eton mess, and several pork pies. And seat and thighs seem to be designed around the J-Lo type.
Otherwise, they're all right. They come with an unfinished hem, and a length of hem tape is provided.
I'll report after I've had them hemmed and put them through their paces etc.
