For many kids, the number 100 is a big milestone. Whether it's counting to 100 for the first time or realizing you just hit your 100th day of school, it's a huge deal! The actual day depends on the school district, but many schools will celebrate 100 days of school in January or February. If your child is taking part in these school festivities, they may want to wear a 100 days of school outfit. Check out our selection of centenarian costumes for kids below!
100-Year-Old Lady Costumes for Girls

Many kids who dress up for the 100th day of school wear centenarian costumes, also known as 100-year-old person costumes. Little girls will look cute dressed in floral print dresses paired with comfy cardigan sweaters and spectacles. These grandma costumes already have most of the items included, but you can always add some extra-chunky jewelry and a DIY walker made from PVC pipe and tennis balls.
100-Year-Old Man Costumes for Boys
| Boys' Old Man Costume | Old Man Costume Kit | Child Grandpa Costume |
Old man costumes for kids have a few essential ingredients: bow ties, plaid and sometimes a pair of suspenders. These grandpa costumes for boys already include everything minus a cane. But if you'd like to customize your boy's look or he had a plaid shirt that you want to use already, you can always use the old man costume kit for kids that comes complete with suspenders, a wig and a bow tie. Other fun items to add to your boy's 100-year-old man costume would be some wire-framed glasses and a sweater vest.
