Frequently Asked Questions

Why does cosplay sizing run small?

Costumes are tailored to a tight, screen-accurate silhouette and run roughly one size smaller than US streetwear. Pick by your actual chest measurement.

How do I measure my chest correctly?

Wear an unpadded bra, run a soft tape level around the fullest point of the chest, snug but not tight.

How do I size a cloak?

Use the height chart. If you fall outside the range, choose the custom-make option.

Are shoes sized separately?

Yes. Shoe sizing is independent and listed in centimeters.

How big is the gap between L and XL?

Typically about 4 cm chest, 4 cm waist, 2 cm length.

Should I size down to look slimmer?

We don’t recommend it — it breaks the proportions of the character.

Can the costume be altered?

Minor seam adjustments are supported. For larger changes, choose custom-make from the start.
