How to unlock Swimwear costumes in Atelier Yumia
Thre are three ways to unlock the Swimwear outfit for Yumia and other characters:
- Season Pass ($44.99 USD)
- Atelier Yumia - Swimsuit Set Pack ($14.99 USD)
- Individual Swimsuit Set ($3 USD per set)
For the Individual Swimsuit sets there are six available, with Yumia and Flammi's swimsuit set coming as a pair for the same price of $3 USD.
On the official Japanese Twitter/X page for the Atelier series, a teaser was posted showing Yumia change into her swimwear costume pre-release. The clip also showed what the party menu will look like with all seven characters in their new outfits.

If you're confused why it says seven outfits but only six playable characters, it's because Yumia's assistant the floating oil lamp Flammi also gets a special outfit. The developer had confirmed the outfits are not limited edition and can be purchased separately at a later date.
How long will the Season Pass last?
While no end date has been confirmed for the Season Pass, the developer has shared that the majority of rewards will not be available until the end of October 2025. This information was discovered by us via the Atelier Product page on the Japanese version of the site. Given this information, it's fair to assume the Season Pass will last at least until November or December.
