Ordered this vest because I'm 6'4" tall, 275 lbs, with a 53" chest and this was one of the few places where big and tall guys can find dress clothes in 3XLT and up. The product is exactly as advertised, a real dark black, sturdy material with a very detailed, nice pattern that looks awesome in neon lights. The material on the back is also black, and has vertical lines in it. The buttons feel a bit loose after two uses, especially the bottom one, but it is normal wear and tear and there is an extra one included.
The sizing is a bit big, and I know I'm not the first person to comment on that here. I learned that by reading these reviews, too. Like I said, I'm a big guy and it is hard for them to know if you need a 3XLT because you're a broad, muscular guy, or because you're built like Jabba the Hut, so plan on a 3XL being a bit roomy, especially around the arms. It fit great across the chest, but was obviously designed for someone with a bit more fluff to them than I have. Even so, the vest looks great, and if I want it tightened up a bit, it's nothing my local seamstress can't knock out in a jiffy.
Happily, if you have any other problems, the customer service for this site is awesome, so you should be able to clear anything up with ease. Not a bad experience, and I will be a return customer the next time I need nice formal wear.
