Just keep wearing it, it will break in quicker than you think. You can keep it rolled up if you want but that doesn't make a huge difference. You can get it tight if you can cinch it up with the help of a power rack. Just put the belt on like you normally would, then take the loose end of it in one hand and with that same hand grab onto the post of a rack. Then will holding the loose end of the belt tight against the rack turn away from the rack so that the belt gets tighter around your waist.
