Jersey is the best option because it's stretchy but you can use other fabrics that have a little give in them. You're fairly tall right? You'll want at least 5.5 yards and since fabric is either 45 or 60 inches wide you can actually get 2 out of it if you cut it in half length-wise. Jersey is good because you don't need to sew it at all. Most other fabrics you'll need to hem or finish the edges somehow so it doesn't fray.
