I've seen their tuxedos, and they are respectable. The vents on the jacket are on the side, rather than the single vent that business suits have, so that's acceptable. The only problem is the jacket pockets do have flaps, but if you just tuck them into the pocket no one can tell. Anyone wearing one will fit in just fine.
No one can also tell whether shirts are bespoke or not, as long as you buy a decent turn-down collar, cotton tuxedo shirt that's fitted properly. Tuxedo shirts shouldn't be monogramed, unless maybe in a white on white monogram which no one would be able to notice anyways.
