Rivumi

Cosplay build sheets

Every piece of the costume, decided.

Name the character. Rivumi splits the costume into components and calls each one buy, make, modify or own — priced against your budget, your tools and the day you need to wear it.

The four calls

Buy
Accuracy is worth more than the saving.
Make
Your tools and hours beat the store price.
Modify
A cheap base gets you most of the way.
Own
It's already in your wardrobe.

Catalog

190 characters, or bring your own

Every character gets a breakdown worked out for that specific costume — never a generic checklist. Missing yours? Add it by name, or upload a reference photo and Rivumi reads the look off the image.

Have a cosplay in mind?

Turn the character in your head into a plan you can actually build — component by component, with the price and the effort attached.
