A spacesuit costume is a favourite Halloween option for many children, and can also be a showstopper at adult parties. As you plan a spacesuit costume, consider where and under what conditions the costume will be worn; choose clothing, accessories, footwear, and base layers according to weather and planned activities.
For a traditional astronaut spacesuit, start with a white or orange base layer. You can find a simple coverall suit with button or zip closures online or at a work supply store; for smaller children, the extra room can allow for additional warm layers for trick-or-treating. Add patches that look like the logos of space missions, or add a flag of your child's choice. You can embroider or use fabric paint to write "NASA" on the front of the spacesuit.
If you are looking for a retro version of a spacesuit, use a shiny silver base layer. You can hunt for silver clothing or start with a simple white or black base, lay flat, and coat with metallic silver spray paint. Allow the paint to dry fully before flipping over. For additional shine, you can add spray-on adhesive glitter to the clothing. For a more adult version of the silver spacesuit, you can use tight leggings and a fitted jacket or long-sleeved shirt. Add a simple strip of dark fabric around the waist to create a belt.
The helmet is one of the most important aspects of the astronaut costume, and has the greatest potential for dramatic appeal. If you have an old bike helmet, you can paint it white and add a visor using slightly tinted plastic; a motorcycle helmet with a retractable visor will also work well. If you have the time, you can make a helmet using papier mache on a balloon; cut out the visor area after the balloon is dry and cut an opening for your child's head.
For a dramatic addition to your spacesuit costume, add a rocket pack. You can create a rocket pack by taking two large packing tubes to create the individual rockets, and glue them together in the middle. Paint the pack white or a shiny silver, and add details with paint or glued-on pieces of shaped cardboard. For a smaller child, you can use empty 2-litre soda bottles. Create shoulder straps out of fabric or silver duct tape. To give the impression that your child is about to lift off, you can add flames to the bottom of each rocket with fire-coloured tissue paper, fabric or cellophane.
