The Classic Junie B. Jones Costume: A Step-by-Step DIY Guide

The core of the Junie B. Jones Halloween costume is a simple, brightly colored outfit that looks like it was pulled straight from a kid's closet. This five-step process is perfect for creating a memorable look for both children and adult Junie B. Jones costumes.

Step 1: The Iconic Bottom Half (The Purple Skirt)

The single most essential piece is the purple skirt. Junie B. is rarely seen without it in the classic illustrations.

• The Skirt: Find a short, pleated, or A-line skirt in a vibrant purple shade. If purple isn't available, a bright pink or red skirt can work as an alternative.
• The Legwear: Pair the skirt with brightly colored leggings or tights. Think pink, yellow, or even striped or polka-dotted tights. This adds a layer of fun and captures her "wacky outfits" style.
• The Shoes: Finish the look with black Mary Jane shoes, ballet flats, or simple black sneakers. White knee-high socks or ankle socks are a must to complete the youthful look.

Step 2: The Cardigan and Shirt Combo

Junie B. often wears a button-up sweater or cardigan over a simple white shirt.

• The Cardigan: A light pink, yellow, or patterned cardigan is ideal. The key is for it to contrast with the purple skirt. A light pink sweater is a very popular choice for the classic look.
• The Shirt: A plain white T-shirt, polo shirt, or collared blouse underneath the cardigan provides a clean base.
• Optional Detail: For a deeper cut, consider adding a few yellow star buttons or a small, hand-drawn graphic to the shirt, referencing a specific book title like Junie B. Jones Is Not a Crook.

Step 3: Signature Accessories (The Hair Bow and Glasses)

Accessories are what truly make the Junie B. Jones costume instantly recognizable. Focus on her hair and, occasionally, her eyewear.

DIY Junie B. Jones Hair Bow

Her hair is often described as short and slightly messy, topped with an oversized, colorful bow.

1. Materials: Get a large piece of ribbon (yellow, polka-dot, or a bright floral pattern) and a hair clip or headband.
2. Construction: Simply tie the ribbon into a large, floppy bow. Secure the bow to the clip or headband with a hot glue gun.
3. Placement: The bow should be worn prominently on the side of the head or right on top, slightly off-center, to capture her energetic style.

DIY Junie B. Jones Glasses

While she doesn't wear them in every book, the purple eyeglasses are an iconic accessory often associated with the character, especially in later books or promotional materials.

• Easy Method: Print a template of cartoonish, round glasses, cut them out, and attach them to a stick as a photo prop.
• Best Method: Buy a cheap pair of plastic novelty glasses (or use an old pair of 3D movie glasses) and paint the frames a bright purple or pink. This is a fun detail for any Junie B. Jones teacher costume.

Step 4: The Prop That Tells a Story

A prop is crucial for Book Character Day costumes as it provides context. Junie B. loves to write and tell stories about her life.

• The Journal: Carry a small notebook or composition book labeled "Junie B.'s Journal." You can write one of her famous quotes on the cover, like "I am very fond of sand" or "I do not like the stupid smelly bus."
• The Box of Crayons: Carry a slightly smushed box of crayons, referencing her artistic and often impulsive nature.

Group Costume Ideas: Bringing Junie B.'s World to Life

The Junie B. Jones costume is fantastic on its own, but it's even better as a group theme. This works perfectly for families, a pair of best friends, or a whole class of teachers dressing up together.

1. Junie B. and Herb (The Bestest Friends)

This is a great duo costume. While Junie B. wears her classic bright outfit, Herb’s costume should be simple and friendly. He is one of the few boys Junie B. genuinely likes. A simple outfit of jeans, a solid-colored t-shirt, and a kind smile will suffice. The key is the dynamic between the two, perhaps holding a sign that says "Bestest Friends."

2. Junie B. and Lucille (The Fanciest Friend)

Lucille is Junie B.'s former best friend, who is wealthy, elegant, and often a source of drama. Her costume should be the polar opposite of Junie B.'s messy style. Think a pristine, frilly dress, a perfectly neat hairdo, and lots of sparkle—maybe a small, expensive-looking handbag. This contrast creates a funny and recognizable pair.

3. Junie B. and Mr. Scary (The Teacher-Student Duo)

Ideal for a teacher and student or two adults. Mr. Scary, the first-grade teacher, is a kind, supportive adult. His costume is a classic teacher look: a collared shirt, a tie, khakis, and perhaps a pair of reading glasses. The humor comes from the name tag: "Hello, My Name Is Mr. Scary."

Final Tips for Embodying Junie B.'s Personality

No Junie B. Jones costume is complete without the attitude! Once you have the outfit, focus on the energetic and impulsive personality that made Barbara Park's books a hit.

• The Hair: Don't worry about perfection. Junie B.'s short hair is often illustrated as slightly tousled and flyaway, adding to her energetic look.
• The Voice: Use a slightly loud, excitable voice and speak with an over-the-top, dramatic flair.
• The Posture: Be animated! Stand with your hands on your hips, make big facial expressions, and generally act like the world's most enthusiastic, slightly confused, and always-opinionated first-grader.
