One size smaller is perfect!
Color: Navy, Size: 10 Years
This suit fit perfect but I did order one size smaller than my grandson normally wears. It is very well made and he can't wait to wear it in the wedding.

Adorable, Complete Set—Great for Special Occasions
Color: Beige, Size: 12, Color: Beige, Size: 12
This suit set is such a great find! It comes with everything you need—jacket, pants, shirt, tie, and bow tie—which makes getting a dressed-up look so easy. It's excellent quality for a suit in this price range.
The linen fabric gives it a nice, lightweight feel and a polished look that works well for both formal and semi-casual events. My son looked adorable in it, and it was perfect for the spring wedding we attended.
What I love:
Complete 5-piece set—no need to buy extras
Lightweight and comfortable material
Classic, stylish look with nice details (lapel, pockets, etc.)
Adjustable waistband is super helpful for fit
Versatile for weddings, holidays, and other events
Fit was true to size based on the chart, but I agree with the recommendation—if your child is between sizes or growing quickly, sizing up is a good idea. I sized up with the hopes that he can wear it again for another event because it looks fantastic!
Overall, a really cute and practical suit set that looks great without being uncomfortable. Perfect for any special event
