I've only needed a tuxedo a couple times, so I just rent when the occasion arises. Last time that was I checked out Chrisanne's. They have a very large variety of tuxes and it sounded like they can also do custom stuff if you so desire. Their gown section was even bigger. Anyway, prices were manageable, though these places always strike me as expensive. Still, was very happy with the fit and look of my suit.
