Great suit!
Size: 8, Color: Mint Green, Size: 8, Color: Mint Green
This suit is gorgeous.
The color is gorgeous
The fit is great.
I like pretty much everything about it.
I even like the clasp in the bow tie. Way better than the snaps or the hooks…
And my son likes it! After telling me he felt embarrassed to wear a suit like two weeks ago, he was actually really liking this one and was trying to think of somewhere he could wear it!
*please ignore the straight-out-of-the-package rumpling in the pictures*
The fabric is nice. It’s really well made. It still fits a teeny smidge big on my son, but he’ll be in it in no time.
It’s a great value. I recommend it.

THESE ARE NOT LINEN - 70%Polyester, 25% Linen, 5% Spandex
Size: 5, Color: Light Grey
Moms be ware this is NOT LINEN! This is 70% Polyester and 25% linen and 5% spandex, so the listing description and material details are misleading. If you're expecting the super soft, lightweight, breathable linen fabric we know and love , this is not it. This is reminicent of those old school curtains. The suit is cute however; but what boys suit isn't cute for that matter? I would say these run a little big. My son who is 5 normally fits a bit snug in a 5 but the length of a 6 is too long. I ordered a 5 and these are long on him, but the suit jacket fits perfectly. They do seem to be sewn well and constructed with quality in mind. I'm just disappointed by the misleading linen claim

Size down if between sizes, well made, classic design.
This linen suit made the perfect Easter outfit and looked even better in person. The color is beautiful and exactly what was shown online, with a soft, neutral tone that feels classic and elevated. The material is lightweight and breathable, which was great because my toddler stayed comfortable and didn’t get too hot. You can really feel the quality in the fabric, and the stitching is well done with no loose threads.
My toddler usually wears a 4T on top and a 3T on the bottom, so I chose a 4T to make sure the jacket fit properly. The shoulders fit great, but the sleeves were a little long. Rolling them gave it a more styled look and fixed the fit easily. The pants were a bit big, so I pinned them for a more tailored fit. If you’re between sizes, sizing down would give a more fitted look overall.
He loved the pockets and kept using them, which was such a fun detail. He also said it was comfortable and was genuinely excited to wear it, which says a lot. The whole outfit looks so polished and dashing, and it’s such a great addition to his wardrobe for special occasions.

Stylish Slim Fit Suit, Great Quality and Budget-Friendly
I absolutely love this slim fit tuxedo suit for kids. The color looks great, the finish is impressive, and it honestly looks way more expensive than it is. I can’t wait for my son to be invited to the next party, wedding, or special event because this outfit is such a classy and adorable choice.
The material feels good quality, the stitching is well done, and the overall design is sharp and stylish. It’s a perfect ring bearer outfit and looks very polished in photos.
Full disclosure, I intentionally ordered a size up for my toddler, so it doesn’t fit him perfectly right now. But even with that mistake, I can tell the sizing is true to size, so I would recommend ordering your child’s actual size for the best slim fit look.
Overall, this is an excellent, budget-friendly suit set that looks amazing and is perfect for special occasions.

linen suit
I love this linen suit! It runs true to size and made really well. The bowtie is easy to put on and adds the perfect touch of class to an already fancy suit. The material is light and airy on the suit. It wears well and can be worn for a casual outing or something more fancy like a wedding. This was chosen for a wedding on the beach and it captured the beach vibe perfectly. I would highly recommend this for anyone looking for something comfortable yet stylish for their little guy. For the quality of the outfit, this is priced way below my expectation.
