"Ordered for my grandson. Really cute and good quality. He received many compliments for his outfit. Only complaint would be price. It’s more than I would spend on him for clothes on a daily basis, but doable for birthday or special occasion."

"I absolutely love the birthday boy jersey with the racing pants!! He will look so cool on his first birthday coming up very soon. Thank you Little Trouble for doing something unique and so cute at the same time. I also ordered the mini racing backpack. It’s bigger than I expected and will be perfect for stuffing his hot wheels and monster trucks and snacks! Love the lining on the inside! I’m sure I’ll be ordering more things."

"Stressed doesn't even begin to accurately express how I was feeling when it came time to plan my son's second birthday. I procrastinated so long that my mom ending up choosing the theme and ordering his outfit. I can be very picky about material because my son has sensitive skin but when I tell you this was the PERFECT birthday outfit. The Birthday Boy jersey is a high-quality, show-stopping shirt that has an incredible fit and feel. My son loved it and so did we! I would recommend for sure. 10/10"

(Which was months before his photo shoot. ) He had so much fun at his shoot! And now he's loving that he can FINALLY wear his jersey whenever he wants! Hahaha. Love little trouble! Wouldn't rock anything else for this kids 5 year old birthday pictures!"
