Aimé Leon Dore, a New York-based apparel brand, will begin selling products in collaboration with Porsche starting at 11:00 AM on October 17, 2025 (EST, which is 12:00 AM on Saturday, October 18, 2025, Japan time).

It seems that you can purchase from Japan at the official online store and have products shipped to Japan, so if you're interested, be sure to get your hands on one before they sell out!
Official online shop:Aimé Leon Dore / Porsche FW25 Capsule
The collection will also be available at Aimé Leon Dore stores in New York and London, as well as at Porsche Design Beverly Hills.
It also appears to be available for purchase from the Porsche online shop, but it seems difficult to ship to Japan from this site, so if you are purchasing online, I think it would be best to purchase from the official Aimé Leon Dore website mentioned above.
The collaboration video is so stylish ^^ (0:30).
