Adorable boys vest! Dress up or down!
Color: Light Gray, Size: 5, Color: Light Gray, Size: 5
Super cute vest! Made of quality materials. The buttons on the front all work very well. My four year old can easily button and unbutton them himself. All 3 pockets in the front are functional cute little pockets. There are vertical line stitchings making this vest look just like dad's. The back is easily adjustable. I will stay I was nervous it was going to be too big for my almost 4 year old - I ordered the smallest size available, size 5 and it actually fits him perfectly. In fact, I could even have gotten him the size 6 and it would have fit so I recommend to size up. It's a breathable vest. The gray color goes with lots of other colors. It's an adorable vest. You can dress it up with a nice suit or dress down. It's adorable with a t shirt and jeans. The inside back is a nice silky material. This vest is very well made - its thick but breathable and a great value for the dollar. I highly recommend.

Perfect Fit and Amazing Quality – Highly Recommend!
Color: Black, Size: 12, Color: Black, Size: 12
I am absolutely thrilled with this boys’ formal vest! The size was spot on—it fit perfectly without being too tight or too loose, which can be hard to find for kids’ dress clothes. The material feels premium, soft yet structured, and it looks much more expensive than it actually is. I ordered it for a wedding where my son was the ring bearer, and it photographed beautifully. It gave him such a classy, well-dressed look while still allowing him to move comfortably through the day. The stitching and finish are top-notch, and the color stayed vibrant even after washing. It paired perfectly with a white shirt and dress pants we already had. I also appreciate how versatile it is—it’ll be great for Easter, family photos, or any other special occasion. Overall, I’m extremely happy with the quality, fit, and style of this vest. Definitely a 5-star purchase that I would buy again without hesitation!

Perfect Suit Great Quality and Value
Color: Lavender Purple, Size: 6 Years, Color: Lavender Purple, Size: 6 Years
I love at how nice this boys suit turned out. The slim fit gives it a stylish, elegant look, and it makes my nephew look so sharp and grown up. Fit true to size. The material feels good quality, not thin or cheap, and it’s definitely nicer than I expected for the price. I really like that it comes as a full set, which made things so much easier instead of having to buy down extra pieces. Love the tie and the vest, so cute. He wore it for a special event and got so many compliments, people couldn’t believe how handsome he looked. It stayed looking neat all day, and he was able to move around comfortably. I could easily see him wearing this again for weddings, church, holidays, or even school pictures. Overall, it’s a great buy if you want your little guy to look dressed up without spending a fortune. Beautiful boys suit, stylish and elegant, great value and quality. Wash inside out, and air dry.

One of the best suits out there!!
Color: Christmas Green, Size: 8 Years
I am not one who write reviews, so the fact that I'm penning this review you should know. These suits are the best, the sizing, the fit, the quality everything is perfect. I bought for my 3 sons and they all fit well, I was worried about the fit because one of my son is slender but tall so length things would be okay but waist toooo big, with this suit everything was on point. Ages: 13-14(about 5"4-5"5 have a little body wouldn't consider husky) got him size 18, 10-11(slender but a little tall for his age) got him size 14, 9yr old(average height and body size) got him size 8. Can't beat the price and for 6 pieces(pants, vest, jacket, shirt, tie, bowtie)

Great buy
Color: Champagne, Size: 6 Years
I bought 3 sizes for my sons to wear at our wedding. They are heavy duty quality material. The dress shirts are a little stiff and snug but also great quality. Would buy again 100%
