Collection: 100th Day of School Costumes

It's the 100th Day of School! This celebration marks 100 days since the start of the school year, it normally falls in the month of February each academic year. It is widely celebrated by teachers and school students to support math milestones from prekindergarten to second grade and help with the understanding numbers up to 100. It's a great opportunity to celebrate with a special costume! Dressing up for the 100th day of school is a fun way to show your school spirit and get into the celebratory mood. One of the most popular fancy dress ideas used by children on this day is to dress up as a '100 year-old', so think cable knit jumpers, walking sticks, glasses and grey hair!

So be sure to check out our selection of 100th Day of School costumes today! Your child will love celebrating this fun day in style.​
