The quality of the suit is very nice. The material feels thick and does not feel cheap at all. My son and I were both very pleased with this three piece suit altogether. We went off of size recommendation and due to personal preference we both agreed if we weren’t already in time crunch we would’ve sized up one size. Still managed to make it work and looked very sharp. He is 5’10” 150lbs - size ordered extra small

Order 1 size larger.

Size: X-Large, Color: Blue White Plaid

Nice shirt. The size is not accurate by any stretch of the imagination. I wear size xl in shirts except for this one. An xl fits like a large. Other than that I like the shirt. I would've given it 5 stars if not for the sizing. I'll give away this one and order an xxl. Just order a size above what you wear and you'll be happy.
