This suit was perfect for my son. The fit was exactly as expected. The quality is excellent for the price—it feels well made and durable enough to last through multiple wears. It doesn’t feel cheap or flimsy at all. It also looks really good on him. Clean, polished, and great for formal events like weddings or parties. Overall, a fantastic value with great quality and a great fit.
