I have a long torso and stumpy little legs. (I'm 5'2"; when I sit next to my 5'10" husband in our dining room chairs, we are the same height but my feet don't touch the ground.) In dresses and skirts, which I don't wear often, I'm happy to wear things that lengthen the leg line, but I strongly prefer trousers and jeans, and I like them low or mid rise.
I also usually wear low heels or flat shoes. Just. Ain't no trick on earth gonna make my legs look ACTUALLY long, so I'm just going to be comfy.
