Boys Blazer Size Guide
Choosing the right size blazer is key to getting a blazer that lasts and also feels comfortable for your child to wear.
Blazers are bought by chest size, so you will need your child's chest measurement to start. To take your child’s chest measurement, measure around the fullest part of their chest. For younger children, place the tape measure a few inches below their armpit and measure their chest there. For older children, the fullest part of their chest might be a little lower. Your child will be able to tell you what feels comfortable. Be sure not to pull the tape measure too tight as this can lead to buying a blazer that is too small.
