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.

V Valanch blue shirt with great workmanship, material, and design at a fair price
The V Valanch blue shirt has a nice collar and great workmanship for a reasonable price. I have a few in different colors and they don't advertise on the shirt (Not for label snobs) so you will look great but not whatever a little logo does for you. These seem as durable as my RL, 3 stripe, and UA golf shirts which are great but the collar isn't as shaped as the V Valanch shirt. Recommend.

I bought three!
Great fit and great material. I bought three for work. The German design is preferable to the standard US polo shirt 👕
