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.

Excellent Suit for the Money. Great, rich details.
Size: X-Large, Color: Black
This is a stunning piece of clothing. The material for the vests and pants are so luxurious and make it look like you spent a lot of money. Great versatility and thick material of great quality. The material is made of a rich fabric that feels subtle and gentle, but with the patterns showing well. It fits well and allows for movement. Whether you are looking for a wedding suit, or something to wear to a gala or bow-tie event, this is it.
