Generation Tux

I'm looking for some advice about Generation Tux. We are not having a bridal party so tux/suit for groom and our dads. Not a big deal to get those to be what we want, but what I'm not sure about if they allow guests to rent suits, that do not match groom and dads. Inhabe no idea if any guest would be interested but thought it could be something to offer up if we hear I don't have a suit to wear. I know women can rent formal wear to an event. Does anyone have any insight if this is possible with Generation Tux
