FAQ

Do you ship internationally?

Yes. We ship to most countries via Japan Post EMS or DHL Express, depending on the destination. Shipping is calculated at checkout. We pack every order in our rigid cotton-covered box regardless of destination. Nothing arrives in a poly mailer.

What is your return policy?

We accept returns within 14 days of delivery for unworn, unaltered pieces with the original tags attached. Swimwear must have the hygiene liner intact. We do not charge a restocking fee. Custom atelier orders are non-returnable, but we will work with you if something is not right.

How do I know my size?

Our size guide is on every product page, with measurements in centimetres. If you are between sizes or unsure, book a complimentary fitting appointment at the Daikanyama boutique, or email us at us with your measurements and we will advise. We would rather you get the right size than the wrong one.

How should I care for the swimwear?

Hand wash in cold water with a gentle detergent. We recommend Eucalan or a similar no-rinse wool wash. Do not wring. Lay flat to dry in the shade. The recycled polyamide fabric is chlorine-resistant but prolonged exposure to pool chemicals will eventually affect the colour, so rinse after swimming.

Can I visit the atelier without an appointment?

The boutique is open Tuesday to Saturday, 11:00 to 19:00. Walk-ins are welcome for browsing and purchasing. Fitting appointments require a booking. Use the contact form. We keep two appointment slots free each day for same-day bookings.

How long does a custom order take?

Four to six weeks from the date we confirm your deposit and finalise the specifications. We send a fabric swatch and a sketch for approval before cutting. If you have a specific date. A trip, a wedding. Tell us at the start and we will tell you honestly whether we can meet it.
