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.

Very stylish & tailored fit
Size: Small, Color: Pink
My husband purchased this suit as a “flower-bro” at my sister’s wedding. Unfortunately the color theme for the wedding was changed so he had to change it out which I was sad about because it fit him very well and looked great! The quality was good and the fit looked tailored.

Loved it. Fit well, sizing was good, however think I could have gotten my son the next size down. We ended up buy a smaller size pants.
