I've used The Black Tux now for two different weddings (not my own). One was a formal tuxedo, the other a charcoal grey suit. In the first case, I did have to get the pants hemmed slightly (but they give you plenty of time and even reimburse up to $15). The second time, the fit was perfect. I have really liked the simplicity of receiving the suit in the mail and sticking it right back in after the event. It definitely beats having to return at a specific store, etc. I would highly recommend this!
Bottom Line: Yes, I would recommend this to a friend
