Space Day splits neatly into two costume lanes, and they're at very different price points. Lane one is the astronaut jumpsuit: a full white or orange flight suit with NASA patches, usually $15-25. Lane two is a space-themed t-shirt with accessories: a NASA logo shirt or galaxy-print top for $8-12, paired with alien headbands or glow stars. Both work, but they solve different problems.
The astronaut jumpsuit is the stronger Halloween reuse. If your kid is into space, they'll wear that jumpsuit for trick-or-treating, dress-up play, and every costume event for the next year or two. It's a solid investment in a costume they'll get mileage out of. The jumpsuit goes over regular clothes, so it's comfortable and easy to put on.
The t-shirt approach is faster, cheaper, and better for kids who don't want to wear a full costume to school. A NASA logo tee with jeans looks like a cool outfit, not a costume — which some kids strongly prefer, especially in upper elementary. Add a few glow-in-the-dark star stickers to the shirt and maybe an alien headband for the fun factor.
What to Wear
For the astronaut route: a kids' astronaut jumpsuit is a one-piece zip-up suit, usually in white or orange, with sewn-on or printed patches (NASA logo, American flag, name tag). Your kid wears regular clothes underneath and just zips up in the morning. Some jumpsuits come with a soft helmet or cap. The full helmet looks great for photos but most kids ditch it within the first hour because it's bulky. A NASA baseball cap is the practical alternative — it stays on all day and still says "astronaut."
For the t-shirt approach: a NASA logo t-shirt is the anchor piece. These are widely available, come in every kid's size, and most kids genuinely like wearing them — they don't feel costumey. Pair with jeans or dark pants and add accessories: alien antenna headbands, glow-in-the-dark star stickers on the shirt, a toy telescope, or a cardboard jetpack (more on that in the DIY section).
Alien headbands are the budget wildcard. They cost $3-5, they're hilarious, and they turn any outfit into a Space Day costume. A kid in normal clothes wearing alien antennae is immediately participating in the theme. These are great for reluctant dressers.
For maximum effort: astronaut jumpsuit, NASA cap, American flag patch, a cardboard or foil jetpack, and a toy walkie-talkie for "ground control communications." Or go the alien route: green face paint, antenna headband, a metallic or shiny shirt, and tin foil accessories.
NASA patches and iron-on stickers are a middle option: buy a plain white shirt and customize it with official NASA patches ($3-5 for a set) or NASA stickers. Your kid gets a unique "space uniform" that they helped design.
Budget Breakdown
Under $10
An alien antenna headband ($3-5) over regular clothes is the cheapest entry point. Or a set of NASA iron-on patches ($4-6) applied to a plain white shirt creates a custom space uniform. Glow-in-the-dark star stickers on a dark t-shirt ($3-4) are another fun low-cost option.
Under $25
A kids' astronaut jumpsuit ($15-20) is the best value for a full costume look. It goes over regular clothes, it's comfortable, and it doubles as a Halloween costume. Or go with a NASA t-shirt ($10-12) plus alien accessories for a lighter approach.
Under $50
A premium astronaut jumpsuit with matching NASA cap, gloves, and accessory set. Or a NASA t-shirt plus a custom-decorated flight vest with patches and a cardboard jetpack. This budget lets you build the full space explorer experience.
DIY & Last-Minute Ideas
The cardboard box jetpack is the showstopper DIY for Space Day. Take two empty 2-liter bottles, spray-paint them silver (or cover in aluminum foil), tape red and orange tissue paper streamers to the bottoms for flames, and strap them to a piece of cardboard that attaches to your kid's back with ribbon shoulder straps. It takes 20 minutes and gets more compliments than any store-bought costume.
Customize a plain white shirt into a space uniform: use a marker to write "NASA" or your kid's name and a mission title. Add aluminum foil stripes at the shoulders. Draw patches on paper and tape them on. Iron-on printer paper lets you print any NASA logo and iron it onto the shirt.
For an alien costume: green face paint, pipe cleaner antennae attached to a headband, and a metallic or shiny shirt (or cover a regular shirt in aluminum foil strips). Make alien hands from green latex gloves or green socks over the hands.
A DIY astronaut helmet can be made from a paper grocery bag: cut out a face hole, cover the bag in aluminum foil, and draw instrument panels and dials on the front. It's not the most comfortable headgear, but it looks great for photos.
Pro Tips for Parents
- 1Astronaut jumpsuits are the spirit week purchase most likely to get reused for Halloween. If your kid is even slightly into space, the jumpsuit pays for itself across two events.
- 2The orange jumpsuit is harder to find than the white one but it's more screen-accurate to real NASA flight suits. White is the classic moon-mission look. Both read clearly as "astronaut."
- 3NASA t-shirts are available everywhere — Amazon, Target, Old Navy — because NASA's logo is public domain. You don't need to buy licensed merchandise; any NASA shirt is legitimate.
- 4Skip the full plastic helmet. Kids take it off within an hour because it's hot and hard to hear in. A NASA baseball cap stays on all day and is more comfortable.
- 5If Space Day and Superhero Day are in the same spirit week, some kids argue that astronauts are real-life superheroes. The jumpsuit might work for both days if you can sell it.
Frequently Asked Questions
- Astronaut jumpsuit or space-themed t-shirt — which is better?
- It depends on your kid. The jumpsuit is a full costume with strong Halloween reuse potential — better for kids who love dressing up. The t-shirt is a casual option that doesn't feel like a costume — better for kids who want to participate without standing out too much. Both read clearly as Space Day.
- Can my kid go as an alien instead of an astronaut?
- Absolutely. Alien antenna headbands, green accessories, or full alien face paint are all fair game for Space Day. Some kids prefer the humor of going as an alien over the straightforward astronaut look.
- Are there non-costume options for Space Day?
- A NASA t-shirt with regular jeans is a non-costume option that still participates. Galaxy-print leggings or a shirt with planets on it also works. Even a glow-in-the-dark star sticker on a dark shirt is enough to show spirit without wearing a full costume.
- Will the astronaut jumpsuit fit over winter clothes?
- Most kids' astronaut jumpsuits are designed to go over regular clothes and have some room. For winter, just size up or skip the puffy jacket underneath — a long-sleeve shirt and the jumpsuit provide decent warmth on their own.
