I made my own wedding dress, it had a tulle skirt. I used 40 yards of tulle. It was only half as puffy as the one you linked because I opted not to wear a hoop or petticoat. You need at least 30-40 yards and a hoop for that kind of volume.
Sewing tulle skirts like that is a SERIOUS P.I.T.A., clear the entire room of anything that can snag the tulle. Remove all cats, dogs and hairy people from the vicinity, vacuum and dust everything in the room before opening your tulle, tulle acts like a magnet for lint & hair. And purchase a steamer, it's the only way to un-wrinkle tulle.
