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.
