Velvet cigarette pants
Slim cotton plain flat fronted trousers (think elderly Japanese male tourist slacks)
Wide leg crepe (has to be crepe) trousers with a high waist
Lightweight tweed trousers
Ghost narrow crepe trousers -- at least these drape nicely and might please the linen trouser fan
Don't try and balance out thick thighs with bootcut. Don't wear linen wide legged trousers, don't have fuss and pleating or pocketing at the top. Don't play about with length (although just over the ankle can be acceptable)
If you are larger you can still wear slim fitting trousers (let's face it, you're not going to disguise largeness like that idiot Gok thinks you can with a wide patent belt) but you can balance out your frame with a structured top or a sturdy heeled, or mad, shoe.
