I don't like the full-length fitted look. I like when slim-fit is juxtaposed against something fuller. Like the wide-shoulder raglan-sleeve tops of the 1980s paired with close-cut stirrup pants, or like the tight-tee/baggy-jeans look that was super-popular 6-7 years ago. Heck, the hallmark of Dior's seminal New Look was the tight bodice contrasted against the flaring, swooshy, extravagant, full skirt.
The full-length skinny look makes slim people look weedy, and is is utterly punishing to anyone who isn't just a bone.
