The overall quality is better than I expected. It is polyester and linen blend, seems easy to care. Like the light green color, muted. Sizing is good, size 10 fits well to my more than average weight 9,5 yo. My only complaint is the tie is not matching the suit as it is shown in the picture. Instead they put an ugly/shiny green tie, which we definitely wont use and need to find something else. Also doesnt have the tissel on the jacket. I kinda liked it🙂
