Emoji Day is one of the more creative spirit week themes, and it's easier than most parents expect. The secret is that almost every popular emoji costume starts with the same base: a yellow shirt. Emojis are yellow circles with one distinctive feature — so a yellow shirt plus that one feature IS the costume. Heart-eyes emoji? Yellow shirt + heart-shaped sunglasses. Laughing-crying emoji? Yellow shirt + tears drawn on the face. Poop emoji? Brown beanie + googly eyes (okay, that one isn't yellow). The formula is simple and adaptable, which makes Emoji Day budget-friendly and fast to put together. The beauty of this theme is that every kid can pick their favorite emoji, and the personalization makes it fun. Some kids go for the funny emojis (poop, tongue-out, upside-down face), while others prefer the expressive ones (heart eyes, star eyes, cool sunglasses). There's no wrong answer, and the costume complexity scales with how much effort you want to put in.

What to Wear

Here are the five easiest emoji costumes, ranked by simplicity: 1. Heart-Eyes Emoji: Yellow shirt + heart-shaped sunglasses. The sunglasses cost $3-5 and do all the work. Draw a small smile on a yellow circle of paper and pin it to the shirt if you want to go further, but the sunglasses alone communicate the emoji clearly. 2. Poop Emoji: A brown beanie or brown hood, large googly eyes (glued or pinned on), and a smile drawn below. This is the crowd favorite for kids who like getting laughs. A brown shirt adds to the effect but isn't strictly necessary. 3. Laughing-Crying Emoji: Yellow shirt + tears drawn on the face with face paint or eyeliner (blue drops under each eye) and a big smile drawn on. This is the most DIY-friendly option — no purchases needed if you own a yellow shirt and have face paint or eyeliner at home. 4. 100 Emoji: A red shirt with "100" written or ironed on. Use red felt, red tape, or a printable iron-on transfer. The double underline beneath the 100 is the detail that makes it recognizable. This is the most popular choice for older kids and tweens. 5. Ghost Emoji: A white sheet with the ghost emoji face (eyes and tongue) drawn or cut out. The tongue sticking out is what makes it the ghost emoji instead of a regular ghost. Simple, funny, and instantly recognizable. For a quick purchased option, emoji t-shirts with the face printed on them are available for $8-12 and eliminate all DIY. Your kid just puts on the shirt and goes.

Budget Breakdown

Under $10

Heart-shaped sunglasses ($3-5) with a yellow shirt from the closet. Or draw the emoji face directly on a yellow tee with fabric markers — the shirt becomes the emoji. The DIY route for most emojis costs nearly nothing if you already own a yellow shirt.

Under $25

An emoji-printed t-shirt ($8-12) is the zero-effort approach. Or buy a yellow shirt ($6-8) plus one prop item: heart sunglasses, googly eyes for poop emoji, or an iron-on transfer for the 100 emoji. At this budget, the costume is purchase-ready with no crafting.

Under $50

A full emoji costume with an inflatable or padded emoji body suit. These are the show-stoppers that make kids the center of attention. They work for spirit week and Halloween and are genuinely hilarious. Just make sure your kid can sit at a desk in it.

DIY & Last-Minute Ideas

Emoji Day is one of the best DIY spirit week themes because the base is so simple. The universal emoji base: a yellow shirt (or a white shirt colored with yellow fabric paint or marker). That's your emoji face background. Everything else is adding features. For heart-eyes: cut two hearts from red construction paper or felt and tape or glue them to a pair of old sunglasses. Or just draw hearts around your kid's eyes with red face paint. For laughing-crying: use blue face paint or eyeliner to draw three teardrop shapes under each eye. Draw a wide open-mouth smile with face paint or a marker on paper pinned to the shirt. Squint the eyes with eyeliner for the laughing effect. For poop emoji: roll brown construction paper into a soft swirl shape and attach it to a headband. Add two large googly eyes (craft store, $2) and draw a smile below. A brown shirt completes the look. For 100 emoji: cut the numbers "100" from red felt or construction paper. The key detail is the double underline beneath the number — that's what makes it recognizable as the emoji versus just the number. Safety-pin or fabric-glue it to a red shirt. The simplest possible emoji costume: write a giant emoji face on a paper plate with markers, punch holes for string, and hang it as a necklace over any yellow shirt.

Pro Tips for Parents

  • 1A yellow shirt is the universal emoji costume base. If your kid doesn't own one, buy a plain yellow tee — it works for Emoji Day, Smiley Face Day, and general dress-up.
  • 2Heart-shaped sunglasses are the single most efficient emoji costume prop. They cost $3-5, they communicate the emoji instantly, and kids love wearing them.
  • 3Iron-on emoji transfers exist and are the fastest way to put a specific emoji face on a plain shirt. Check craft stores or Amazon — they take 5 minutes with a household iron.
  • 4The poop emoji is always the most popular choice among elementary kids. If your kid picks it, lean into the comedy — the bigger the googly eyes, the better.
  • 5For older kids who think costumes are embarrassing, the 100 emoji on a red shirt is subtle enough to feel cool rather than costumey.

Frequently Asked Questions

What if my kid doesn't own a yellow shirt?
A plain yellow kids' t-shirt costs $5-8 on Amazon. It's worth buying because yellow shirts work for Emoji Day, Smiley Face Day, and general spirit week use. In a pinch, a white shirt with a large yellow circle drawn or pinned on the front works too.
Can my kid be an emoji that isn't a face?
Absolutely — the rainbow emoji, the fire emoji, the star emoji, and the lightning bolt emoji are all doable with colored clothing or cut-out shapes. Any recognizable emoji works for this theme, not just the face emojis.
Are full-body emoji costumes practical for school?
The inflatable or padded emoji body costumes are hilarious but can be hard to sit in at a desk and difficult to use the bathroom. For school, a t-shirt-based emoji costume is more practical. Save the full-body suit for Halloween or a short event.
