What Are Boob Bags?

Have you ever wondered how some people manage to achieve that perfect chest shape for their cosplay characters?

Let me introduce you to the magical world of boob bags! These amazing little inventions are specially designed fake boobs that can be worn under your costume to give you those voluptuous curves and enhance the overall appearance of your cosplay.

So why should you consider using a boob bag for your next cosplay project? It’s simple – authenticity and confidence. When we put on our costumes, we want to feel like we’ve truly transformed into our favorite characters, right?

Boob bags help us do just that by giving us the accurate body shape of our chosen character. Plus, they’re super comfortable and easy to use.

Why Would You Use Boob Bags In A Costume?

First off, let’s talk about accuracy. If you’re aiming for an authentic portrayal of a character with specific chest proportions, boob bags can help achieve this with ease. They offer additional coverage and support while maintaining the overall look intended by the original design.

Confidence plays a massive role when stepping out as your favorite character at conventions or other events – who wouldn’t want to feel like they’ve nailed every detail of their chosen persona? Furthermore, these clever little accessories provide added security and peace of mind for cosplayers wearing revealing costumes. Knowing everything will stay put throughout the day allows you to focus on enjoying the event instead of constantly worrying if any wardrobe malfunctions are lurking around the corner.

How To Make A Boob Bag


  • Regular Craft Foam
  • Masking Tape
  • Pen or Pencil
  • Scissors
  • Rubber Cement or Contact Cement
  • Hot Glue Gun
  • Yellow Upholstery Foam
  • Stretch Knit Fabric
  • Liquid Latex (Flesh Tone)
  • Popsicle Sticks
  • Baby Powder
  • Sewing Supplies (needle, thread)
  • Optional: Airbrush and Airbrush Paints


  1. Draw and cut out a large teardrop shape on the regular craft foam. Make several darts (slits) in the foam to create a curved 3D shape that covers your breasts. Temporarily tape the darts with masking tape, mark the cuts, remove the tape, and cut the pieces.
  2. Use rubber cement or contact cement to glue the darts together. Reinforce the seams on the inside with hot glue.
  3. Try the foam cups on and adjust the shape if necessary to cover your breasts fully and suit your desired cleavage style.
  4. Cut a piece of yellow upholstery foam to cover the craft foam shape. Stretch the foam onto the shape without ripping or cutting darts. Use clips to hold the foam in place, then glue it onto the craft foam with hot glue. Trim and shave the foam edges to create a smooth shape.
  5. Find a stretch knit fabric in a suitable color. Stretch the fabric over the foam cups and use pins or clips to hold it in place. Hot glue the fabric edges to the inside of the cups.
  6. Apply flesh-toned liquid latex to the fabric using a popsicle stick. Start with a thin layer and let it dry. After each layer, brush on baby powder to prevent sticking. Repeat until you achieve a skin-like texture (usually 2-3 layers).
  7. For the final layer, pour liquid latex directly onto the boob bags and manipulate them to cover the entire surface evenly. Let any excess latex drip off. Once dry, brush with baby powder.
  8. Trim any dried latex drips from the edges of the boob bags.
  9. Optional: Airbrush the latex to match your skin tone perfectly, or use makeup as an alternative.
  10. Lastly, add straps made from leftover scrap fabric so that your boob bag stays securely in place while you rock your amazing cosplay creation! Sew straps onto the excess fabric inside the boob cups and reinforce the stitches with hot glue. Add a small piece of fabric between the breasts to help hold them together.

Alternatives To Boob Bags

Now that we’ve explored the world of boob bags, let’s dive into some alternatives for achieving a desired bust shape in cosplay.

Like putting together pieces of a puzzle, finding the right solution requires creativity and understanding what works best for your body and costume.

One popular option is silicone boob shapers, which can be adhesive or non-adhesive depending on your preference. These nifty little wonders are designed to mimic the look and feel of natural breasts, making them an ideal choice for those who want a realistic appearance without committing to a full-on boob bag.

Another alternative would be foam bra inserts – they’re lightweight, easy to use, and perfect if you only need a slight boost in volume.

If you’d rather not deal with any additional accessories at all, consider adjusting your costume design so that less skin is shown. This way, you can still maintain character accuracy while feeling comfortable and confident throughout the entire event.

Remember that cosplay is about expressing yourself creatively and having fun! Don’t feel pressured to conform to certain expectations or standards when it comes to portraying characters with different body types.
