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.
