This Kids 100 Days of School Costume turns your child into a kindly old gentleman for the 100th day celebration — complete with flat cap, round glasses, and a walking stick that adjusts to three heights. Seven pieces ready to wear, no sewing or complicated assembly.
The look is classic mid-century old man: light blue collared shirt, brown plush vest, bright yellow tie for a cheerful pop, and mauve trousers with an elastic waist for comfortable all-day wear. The blue striped flat cap and wire-frame glasses seal the character without needing makeup or grey hair spray. Walking stick extends from 50cm to 100cm so your child can lean on it dramatically.
Perfect For
100 Days of School: The natural pick for the 100th day tradition where kids dress as if they're 100 years old — teachers love the instant recognition, and it photographs beautifully for the school memory book.
Grandparents' Day & School Concerts: Works for any event celebrating elders or historical figures, from nativity plays needing a wise village elder to Book Week characters like the old man from The Snail and the Whale or The Tiger Who Came to Tea's kindly neighbour.
Dress-Up Play at Home: The adjustable walking stick and comfortable fit mean this costume gets worn long after the school event — perfect for imaginative play, story time, or backyard performances.
How to Wear It
Pair with black school shoes or dress shoes to complete the old-gentleman look. The vest layers over the shirt with no closures, the tie is pre-tied (just slip it on), and the cap fits snugly with an inner elastic band. Adjust the walking stick to a height that lets your child rest their hand comfortably on top — the three extension options mean it grows with them.
Parent FAQs
Q: What size should I order for the 100 Days of School event?
Check the size chart for chest and height measurements. The elastic-waist pants and adjustable cap give you some flex, so if your child is between sizes we'd say go with their usual clothing size. The shirt is cut generously through the shoulders.
Q: Can they wear this over their regular clothes, or does it replace them?
This replaces regular clothes — it's a full outfit (shirt, vest, pants, tie, cap). The shirt has long sleeves and the pants have an elastic waist, so it's straightforward to get on. Glasses sit comfortably over most kids' faces; if your child wears prescription glasses daily, the costume glasses fit over the top or can be skipped.
Q: Is the walking stick safe for school use? Will it break?
The walking stick is lightweight and designed for costume use, not as a weight-bearing aid. The four sections screw or snap together securely, and it's sturdy enough for a day of dress-up. Supervise younger kids with the stick during playtime — it's a prop, not a toy to swing around the playground.
Q: Does this work for Book Week, or is it only for the 100th day?
It's perfect for both. For Book Week, your child can go as the old man from The Tiger Who Came to Tea, the elderly neighbour in Possum Magic, or any wise elderly character from their favourite chapter book. The flat cap and glasses are instantly recognisable, and the costume reads clearly as "kindly old gentleman" without needing a specific book tie-in.
Care: Hand wash cold, hang to dry. Store the walking stick assembled or in its four sections.
