Great quality, we could've sized up.
Size: X-Large, Color: Black, Size: X-Large, Color: Black
This suit was absolutely stunning! My son looked amazing in it for homecoming. With him being 6'4", the length was perfect, but it was a but too snug in his thighs, as he is a muscular athlete, and he was a bit worried sitting down in it!😂 Nonetheless, it held up well for my huge Samoan baby, and he got many compliments on it. We also found a bow tie to match it perfectly with the same pattern.

Jackets made too small and too tight
Size: X-Large, Color: Black
My son is 6'2" & 185 lbs and normally wears a 36 in pants. Site recommends a large, but I ordered an xxl based off the reviews. It was way too big in pants and jacket! I then ordered the large and the xl to be on the safe side because prom was fastly approaching. The large was too small! The xl was okay, but not perfect. Somehow it seems they need a suit size in between the xl and xxl, leading me to think they were just sewn wrong. The pants were extra long (good thing for us), they had to be hemmed. He did need a belt, but not by much. He was able to bend and sit with the pants on. The jacket however still runs small in my opinion. It is too tight in the arms, making it difficult to move. It is also on the short side in sleeves and length. It definitely shows when raising your arms. We chose this suit because we THOUGHT it was the pattern of his date's prom dress; turns out it wasn't. But it matched the vest we bought perfectly. This suit is made of a thin silky material and it runs small. And the pockets ARE useable. You just need to find the starter hole and remove the thread (if closed). I would recommend buying a different suit unless you order it bigger and have the time and money to alter it. Oh, and it will take a while to get a refund. Suits ship to you fast, but goes back slow. You gotta wait til the company receive the item, then still wait for the refund.

Boys Formal suit
Size: 10 Years, Color: Champagne, Size: 10 Years, Color: Champagne
This formal suit is perfect for weddings, or any formal function. It is true to size. The pants run a little long. The material is shiny. The suit is worth the money, and actually looks like it cost more than what it did. There is not adjustable waist. You have to wear a belt with it. This outfit will make you feel rich in spirit. My son was so adorable in this outfit.
