GQ KIDS...For the love of being FLY!
Size: 8, Color: Sky Blue
I am highly suggesting this suit for purchase because the color alone is a standout and will have people asking where did you get the suit from? The length of the bowtie is adjustable, the color is bright and lively, the fabric is pure quality. You can run a hot iron over it or a steamer to get the fold lines out of it from how it was packaged, but it seems that even if you just hung it up in the bathroom while running a hot shower, the wrinkling would drop. I think the purchase price is good for all that you get which is a quality blazer, great slacks and a bowtie. It's a one stop shop for a graduation event, dinner, a formal party or even a photoshoot. My nephew wears a size 7 or 6-8, so I ordered a size 8 to be safe and it fits nicely.

Cute sky blue linen suit for toddler!
Size: 3, Color: Sky Blue, Size: 3, Color: Sky Blue
I got this Trasign Kids Linen Suit in sky blue for my 2 year old, thinking my wife said “blue” (turns out she meant navy or something darker 😅). I actually really like the light, airy sky blue. It’s fresh, summery, and looks adorable on him for photos or special occasions. My wife? Not so much. She immediately said “baby blue ugly” 😅😅
On the plus side:
• Soft fabric – linen blend feels gentle and breathable on little skin, no itchiness or stiffness.
• Nicely packaged – arrived with very little wrinkling (barely needed steaming), which is a win for linen.
• Good fit for a toddler – true to size, easy to button, and the shorts/pants have adjustable waist for growing kids.
• Looks sharp once on – the set gives that classic little gentleman vibe without feeling over the top.
It’s a quality piece overall, just a classic case of “what one spouse loves, the other doesn’t” on the color. If sky blue works for your family (or you’re shopping solo like me 🤣), it’s a solid buy.

Perfect fit and great quality for the price
This suit was perfect for my son. The fit was exactly as expected. The quality is excellent for the price—it feels well made and durable enough to last through multiple wears. It doesn’t feel cheap or flimsy at all.
It also looks really good on him. Clean, polished, and great for formal events like weddings or parties.
Overall, a fantastic value with great quality and a great fit.

Missing items
Color: Sky Blue, Size: 16
Was missing the tie that is supposed to come with it and it looked like it was tried on and thrown back in the bag. The sleeve to the jacket were rolled up.
