Suit looks great for fun formal events
Size: X-Large, Color: Green
The style and fit are great. I did notice a white thread in the shoulder poking out. I used a marker to darken it so it was not noticeable but other than that this suit really looks great. We have a music event in a couple of weeks that I am wearing this to and think it will delight as a sharp but different. I was also happy that it did not require alterations, sleeve length was on spot and everything fit great (XL) also this is a slim fit but I am not that slim and it fit nicely on me. As long as it doesn't disintegrate during the event I will consider this money well spent.

Fit was nice. Pants were a tad bit snug, but the elastic waistline made them doable. Jacket was a perfect fit, just wish I could have pick my waist size..
