Handsome Son, Great Suit
Color: Brown, Size: 8, Color: Brown, Size: 8
We ordered this for my 9 yr old son who walked me down the aisle when I got married. It fit perfectly, was a great value, good quality, and looked great on him! The tweed pattern and color were perfect for the wedding.

Adorable!!!
Color: Green, Size: 3, Color: Green, Size: 3
This suit is adorable! I got it in 2 colors. Made the perfect Christmas picture outfits. The quality is great. I got them 1 size up so they could fit in it longer, and size up was a little big as expected. Im happy they will fit in them for another year.

Well made and very nice material.
Color: Dark Brown, Size: 10
This is a great suit the quality material and the color is better than expected. The slacks have waist adjustments that help with comfort. Definitely worth the price. I give it 4 stars because it was supposed to be a slim fit but the jacket is really loose and not as form fitting as I expected, however the suit is worth the price. My son loves it ! Color is perfect for him!

Returned ...
Color: Dark Brown, Size: 20
I ordered the dark brown suit which my son loved. once I looked closely there seemed to be cat hair on it, it looks like it was washed as well, which caused the material to rise and become damaged.
