In this tutorial, we will break down each piece of the outfit. You can easily assemble this entire look using simple, low cost items found online.
Let us dive into the details so you can build this heroic outfit step by step with absolute confidence.
Complete Costume Breakdown
Clothing & Core Pieces
The absolute foundation of this vintage cosplay is a retro red and blue swimsuit. You should look for a halter neck suit with classic cuts to match the 1940s aesthetic.
To make the swimsuit look completely accurate to the comics, you will need to add bright white stars. We recommend using star patches and fabric glue to attach these stars to the blue sections.
Next, you need to secure a thick red waist belt around your middle. This accessory defines the iconic retro silhouette and ties the patriotic color scheme together beautifully.
For the lower half, you will combine red, white, and blue striped socks with bright blue boots. The high striped socks should peek out just above the top of your boots.
Accessories & Details
Let us discuss the key accessories that make this DC Comics character instantly recognizable. First, you will definitely need to purchase a classic pair of vintage aviator goggles.
You can wear these goggles resting on top of your head or pulled down over your forehead. They add a perfect retro pilot feel that completes the classic Bombshell theme.
Next, slip on a pair of blue gauntlets or fingerless gloves over your hands and forearms. You can customize plain blue fabric sleeves or purchase pre-made athletic arm covers.
Do not forget the small details that bring the character to life on your skin. Apply temporary star tattoos to your shoulder or face for a fun and accurate detail.
Finally, the most important prop for this costume is the iconic cosmic staff. You can buy a premade toy staff prop or build a lightweight custom version yourself.
Cosplay Tips
1. Take time to secure the white star patches with strong fabric glue or simple hand stitching.
2. Break in your new blue boots at home before the convention to avoid getting painful blisters.
3. Adjust the red belt so it sits comfortably on your natural waist and does not slide.
4. Style your hair in classic 1940s victory rolls or soft curls to complete the vintage look.
5. Practice posing with your cosmic staff prop in front of a mirror to find your angles.
6. Pack extra temporary star tattoos in your convention bag for quick touch-ups during the day.
Character Vibe & Styling Notes
Stargirl is known for her bright, energetic personality and confident, heroic stance at all times. Keep your posture upright and smile brightly whenever you pose for convention photos.
For your makeup, go for a classic retro look with bold red lipstick and simple winged eyeliner. This clean and striking style matches the classic 1940s pin-up aesthetic perfectly.
You can style a bright blonde wig with thick, bouncy curls for a comic book look. If you use your natural hair, a curling iron and strong hairspray will work well.

Building a Bombshell Stargirl DIY costume is an incredibly fun and rewarding project for any cosplayer. It offers a comfortable, highly recognizable, and photogenic option for your next event.
With these simple steps and items, you are ready to shine bright like a star. Grab your cosmic staff, strike a confident pose, and go save the day!
