Men's Tuxedo

Men's tuxedo worn a handful of times, but it's about 12 years old. Unfortunately, at the time I weighed around 175 pounds and now I'm closer to 155. I looked at getting it tailored, but they recommended against it. The pants have a black pipe along the outside and come with suspenders. The inseam is 31 inches. I'm 5'9". The tuxedo shirt is 15.5" and it comes with a plain, black bow tie. I would translate the jacket at about a size 40 and the waste, back then, closer to 33-34 inches.
