Once you know what type of fish costume you want to make, start gathering materials. This could include fabric, glue, felt, scissors, cardboard and other craft supplies. Make sure to have everything you need before starting the project.

You can also use sequins, beads or other decorations to give your fish costume some extra sparkle. To complete the look, create a headpiece for your fish costume using foam, felt or cardboard.

2. Avoid Sharp or Pointed Edges

Fish costumes often feature fins or other protruding pieces that could potentially cause harm if they’re too sharp or pointy. Make sure to round off any edges or use materials that are already smooth and safe to touch.

3. Check for Choking Hazards

If your fish costume includes small pieces like sequins or beads, be sure to securely attach them so they don’t become choking hazards. It’s also a good idea to avoid using any small, loose parts that could easily come off the costume.

4. Test the Costume for Comfort

Before finalizing your fish costume, have the wearer try it on and move around in it to ensure that it’s comfortable to wear. Make any necessary adjustments to improve comfort, such as adding padding or adjusting straps.

5. Consider Visibility

If the costume covers the face or has a hood, make sure that the wearer has good visibility. Use mesh or another translucent material for the eyes if needed.

6. Ensure Proper Fit

A well-fitting costume is not only more comfortable but also safer to wear. Make sure that the costume fits snugly but not too tightly, especially around areas like the neck and wrists.

Make Sure That 
The Costume Fits

Overall, it’s important to use your best judgment and common sense when creating a fish costume. Take the time to properly plan and construct the costume, and address any safety concerns before it’s worn. With a little extra effort, you can ensure that your fish costume is safe and enjoyable for everyone involved.
