"This was an impressive buy, the shirt is silky smooth, it fit well and size perfectly. My son wore it for his TK promotion and it definitely turned some heads. Little trouble has become a staple in our household. We love the quality."

"i got this for my 4 year old and it’s so soft and breathable and since the buttons are snaps, he can do it himself. i ordered him a 5t (he’s newly 4) and it is a bit big but he will grow out of it in no time i’m sure! super cool shirt for my super cool dude!"

"My son is very unique and didn't like following a crowd so coming across this brand has been amazing! He got this button up and the cargo khakis for picture day and has been complimented many times! Everything is made so well and can't be flawed! I will be a patron of this company as long as they carry his size! My daughter also is very excited to get some outfits!! My only wish is that I found them sooner so he could have with them since he was little!!"

"I bought this shirt for a wedding that I took my 2yr old son to with me. It is a great shirt! He got A LOT of compliments! He wore it with a black bow tie and it looked really nice! Everyone that touched him commented on how soft the shirt is. It was a bit larger than I had expected. I ordered the 18-24 month size because I wanted it to fit snug and it fit well, but it was a bit larger than I anticipated. But overall I absolutely LOVE the shirt."
