If you have long legs and a short torso How can you make your legs look shorter?

Wear a dress that comes to about your knees or just a tiny bit past them, and wear wedges or flats, whichever you prefer.

For a more casual look, wear flared jeans and some cute flat shoes with them, and a Halter top that is long and flowing. And maybe a sweater over it that has bulky sleeves.
