Great Boys Suit Vest
Color: Black, Size: 12, Color: Black, Size: 12
I recently had a chance to pick up this boy's suit vest for my upcoming wedding, and it is absolutely perfect. It fits my son so well, running very true to size. The material is so silky smooth and soft, he absolutely loves it. He's autistic and has a thing about different fabrics and this does not irritate or bother him at all. It is going to be perfect over his long sleeve button down shirt. The best looks amazing on him, and the black color is definitely a very dark true black. It is such a great value for the money, you will not be disappointed! I highly recommend picking this up if you need one for your boy or if you have a family member who needs one for an upcoming event.

Boys vest
Color: Black, Size: 8
The vest looks nice. It seems well made and looks high quality. The fabric is nice. The buttons seem very sturdy. The vest is lightweight and shouldn’t be too sweaty. It’s a nice versatile piece. Can be dressed up or down. The fit is a smidge awkward on my boys, but they still like it.

Looks very nice and sizing is right
Color: Navy Blue, Size: 14, Color: Navy Blue, Size: 14
I ordered this for my 13-year-old who currently wears a size 12-14. He's closer to the 12, but has enough clothes in that size, so I ordered the 14 in navy blue. He chose the color, although it took him a while to decide. My kids so far have preferred not to go to school dances or dressier school functions, but I try to keep an outfit on hand in case they need it, and he does have to dress up a little for school band performances. He doesn't really have any kind of clothing preferences (yet), and is just as likely to look dressed up as he is to wear something completely wrinkled (but clean). This vest fits as expected. It is a bit large on him to the same degree that the other size 14 clothes he has are. He is pretty skinny, so while I think it would fit someone who is more average sized, I'm not sure how well it will do on huskier sizes. It has a nice buckle on the back as most men's vests like these have, so it can be adjusted in that sense. The navy color is a bit of a brighter shade than your average navy, but not outside of the normal range for navy. I like it. It’s hard to get the exact color in pictures. The fabric and construction both seem to be good quality. The fabric feels average compared to my husband's dress vests, better than the lower quality/cheaper ones and not quite as nice as the ones he spent more on. This boy's dress vest is currently being sold for approximately $20, which I think is great for a nice dress vest like this.

"Navy Vest & Pocket Square Charm; Formal Polish for Perfect Pairing
Color: Navy Blue, Size: 8, Color: Navy Blue, Size: 8
This very charming boys navy blue vest pairs perfectly with the accompanied pocket square, adding formal charm to dockers or navy khakis. My boys look dapper in matching sets. A timeless style that elevates any outfit. Made with quality fabric that appears to resist wrinkles, with the pocket square folding neatly for that polished touch. Comfortable and event ready.

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.
