Poorly sized
Color: Black, Size: 12 Years
My son is a size 12 , but this outfit was 2 times his size. The shirt was too large and pants were ridiculously wide. I have to return it

Samsonite? I was way off!
Size: 8, Color: Light Blue, Size: 8, Color: Light Blue
Linen was a nice enough material and slightly distracted from the dumb&dumber blue motif. The regular suit material would have been a full homage. It is what he wanted so this was a fair compromise. Stats/ he is a size 8 in most brands, 51in and 60lbs. Purchased an 8.
A size 7 would have been a better choice and more tailored look but this fit fine in the important places and he has room to grow. Short notice, quick shipping and fair quality for the price. May your Harry Dunne love it as much as mine did.

Great price without skipping on quality.
Size: 12, Color: Light Green, Size: 12, Color: Light Green
Perfect for 8th grade dance. This 3 piece suit fit perfectly. It look so sharp for his dance. This would also be nice for a wedding. I plan on getting a few different colors the price makes it affordable but doesn't skip on quality.
