A great value for the price.
Color: Black, Size: 12
I am very impressed with this suit! I got this for my boys for a formal dinner event and it didn't disappoint. This set is a great value and much better than buying all separate pieces. The fit is nice and the quality good enough for what we needed it for. Not top of the line but it doesn't look cheap and the black and white colors are true and crisp. You will definitely need to get this steamed or pressed but overall it's been a wonderful addition to my boys' wardrobe.

Little gentleman level : EXPERT!
Color: Black, Size: 4
This tuxedo set transformed my little guy into the sharpest-dressed attendee at the wedding. The slim fit blazer and double-breasted design look incredibly polished without being stiff or uncomfortable. The vest adds a nice touch of formality, and the bow tie? Instant charm overload. The pants fit true to size and have just enough stretch for toddler wiggles and running around (because you know he’s not just going to stand still). We got compliments all night—several people asked if it was custom-made! If you want your kiddo to look dashing and feel comfy enough to enjoy the party, this set nails it. Plus, it’s perfect for weddings, holidays, or any time you want to make the family photo extra classy.

Great suit
Size: 12, Color: Mint Green, Size: 12, Color: Mint Green
Very nice suit. Love the material. My 11 year old is tall and slim- 5’3”, 80 lbs. I got a size 12 for the length. The jacket fit perfectly, the pants was good length and has elastic in the waist to adjust for size. Overall, it’s a good suit and I’d recommend it.
