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.

Good but not cloth material
Color: Beige, Size: 8
Suit was good but material was kind of old fashioned. In Pictures cloth looks very different compared to in real. Fitting wise I m satisfied but not cloth material.
