Great value
Size: 10-11, Color: Black
We bought 2 of these because our suit rentals for our wedding didn’t come with full vests for the children (Men’s Wearhouse gives you bibs for kids), and we live in Texas, so we didn’t want the boys to have to wear a full jacket during the reception in the heat.
These fit really well and matched the suits that we rented.

Get it!
Size: 10-11, Color: Blue Plaid
Another must buy on my list! Color, size and length were all good. I was a bit surprised as to the thickness of the vest, not heavy, but well made. Definitely value for money!
