Boys linen fabric suit
Color: Light Green, Size: 16
Boys suit set in a lighter green color. This suit is made with good proportions and seems to fit well. The sizing seems slightly big so maybe size down one size. The fabric does wrinkle easily so be aware that sitting and folding the suit may cause wrinkling. Otherwise it is a very nice suit for a formal occasion. It comes in many good colors.

Nice elegant suit for any occasion.
Color: Light Blue, Size: 12, Color: Light Blue, Size: 12
The suit set is very nice, the fabric material is durable and soft. Overall stitching is tight with nice surging of the hems and great construction on the shoulders. Buttons and button wholes are well done. I'm going to iron in the creases on the front of the pants because they weren't folded properly for shipping. The material does hold on to wrinkles so don't be afraid of your iron to get a super sharp look.
The color is a soft baby blue that stands out in a crowd of black suits. With the option of an elastic tie or clip on bowtie this is everything you need to make him look presentable for a variety of occasions.
My only complaint about this suit kit is the dress shirt is stiff and thin. I found some loose threads that I don't trust to not get played with. I'll probably trade it out for something with a little more cotton.
As far as cost goes mid range, but definitely worth the cost. I might consider something with a vest if it's a super formal event, but I'm very happy with how this suit comes together.

Modern luxury with summer fabric that performs above its price!
Color: Beige, Size: 14, Color: Beige, Size: 14
Wow! My son wore it for Easter Sunday and this suit fits the bill! The linen material is spot on--not too heavy and not too light especially since the weather is warming up now. The jacket is quality made--the design is modern executive, the stitches are strong no flaws to note. The pants are tad bit longer but that's okay, build quality is also great. The white shirt is decent and matches well with the rest of the set. The bow tie and tie itself is a great complimentary to the set, though optional to wear. The whole set just has that quality you would really look for in the price range you would want to pay. Overall, best value for for the, wear right outside the bag, maybe a light ironing otherwise it's perfect! I highly recommend it, no complaints here very happy with this suit!

Heavy linen character, but a beautifully tailored suit!
Color: Beige, Size: 4, Color: Beige, Size: 4
This is a really nice linen suit! The jacket is beautifully made and well-tailored, with a fun speckled texture that has lots of pretty color variation (we ordered the beige). When I placed it side by side with a similar linen suit from another brand, the difference in the linen texture was really noticeable — this had a much stronger linen character that stands out!
It has three useful pockets on the outside of the jacket, which is great for little hands. The only downside is that one of the inside pockets is just for show (faux), which was a bit surprising and somewhat disappointing for my little guy.
The pants have pockets too, but they aren’t very deep — perfect for small treasures, but not much more. The pants are made from a lighter, thinner single-layer linen compared to the fully lined, double-layer jacket, which makes sense for comfort and easy movement.
The pants didn’t come with a front crease ironed in, so you’ll want to press one yourself. The linen did pick up some creases from being folded in the package, but it doesn’t seem quite as wrinkly as some other linen fabrics I’ve tried. Still, like most linen clothes, especially for boys, the pants will need occasional ironing to keep them looking neat and crisp, especially after a day of play and general wear. The structured, lined jacket stays looking smoother and more put-together with less effort.
It also came with a bow tie, a neck tie, and a tuxedo-style white shirt as extras. The ties aren’t great quality — they’d work fine for quick photos but probably won’t hold up to much actual wear. The formal white shirt feels a bit funny paired with the casual linen suit, but I don’t mind at all. We already have white shirts that we prefer, so we’ll use those instead. For us, the extras are really just bonus items we won’t plan on using.
Overall, it’s a handsome little suit that’s perfect for special occasions like weddings, family photos, or holiday events. My kid looked adorable in it! The stronger linen texture on the jacket gives it a premium feel that I really like. Just be ready for a bit of extra care with the pants to keep everything sharp.

Great suit set
Color: Light Grey, Size: 4
It is incredibly attractive and includes everything a young child needs for a special occasion.
The material is a 75% polyester and 25% linen blend, and the outer fabric feels remarkably smooth. Its unstructured design allows for an attractive, natural drape, and the blend conveniently allows for machine washing at home.
As is typical with linen-based materials, the fabric can be naturally stiff and prone to wrinkling, so I recommend ironing or steaming it before use. The lightweight feel makes it an excellent choice for the spring, summer, and fall months.
Overall, this suit offers exceptional value for the price.
