Here is our Lady Short Leg's duchess Keira Knightley looking incredible in high waisted trousers. Considering that she is aware of her proportions, it appears that she is choosing her fashion accordingly, and luckily for her and for us all high waisted jeans and trousers are quite in style. Those billowy trousers of hers paired with the nautical striped top or the deep V neck blouse is thoroughly a good outfit for us (besides a dress) and very chic too. I especially like the ones with the four buttons, however in some of the looks, it would have been better to match the shoe color to the trousers, for a more elongating look.
A baggy/wide leg pant (like hers), as supposed to tight high rise one, is better as it does not draw attention to a long back.
