Put on your base layer of moisture-wicking compression shorts or leggings to prevent chafing during the run.
3
Layer the lightweight athletic tutu over your shorts, ensuring the waistband sits comfortably and securely.

Apply the iron-on emblem or felt logo to the chest of your solid-color tech shirt before putting it on.

Secure your hair back and put on the matching sweatband and wristbands to complete the athletic look.

Makeup & hair

Keep makeup minimal, waterproof, and sweat-resistant. Secure hair tightly in a high ponytail, athletic braids, or a bun to keep it out of your face during the race.

couples: Go as Forrest Gump (yellow polo, red cap, running shorts) and Jenny, or a classic superhero duo.
group: Dress as a pack of Minions with yellow tech shirts, denim-print running shorts, and yellow headbands.
kids: A lightweight superhero cape attached to a standard t-shirt with velcro, paired with running sneakers.
Plus size: Opt for high-waisted, wide-band compression leggings paired with an A-line athletic skirt or tutu for maximum comfort.

Tips

Never wear anything new on race day; take your costume for a test run of at least 2-3 miles to check for chafing or bouncing.
Avoid heavy masks, capes that drag, or handheld props that will fatigue your arms over long distances.
Ensure your race bib remains fully visible on your front, pinning it securely through your tech shirt or using a bib belt.
Check the race guidelines beforehand, as some events have strict rules regarding masks, capes, or toy weapons.
