One Piece is just one of the brands that HIPSHOP works with. They also collaborated with Hatsune Miku and produced a range of Vocaloid-inspired underwear earlier this year.

The new One Piece collection centers on the most recent major storyline from the anime and manga, known as the “Egghead Arc.”

It adds a total of 24 new designs to the already extensive lineup, featuring characters in their Egghead Arc attire.

The brand’s core concept for the collaboration is “Wear them! Decorate with them! Enjoy them!,” inviting fans to treat the items as both daily apparel and display pieces.

The underwear itself is made from a quick-drying, elastic polyester material, making it suitable for both casual wear and for use as activewear.

As a special promotion, customers who purchase items at HIPSHOP’s physical retail stores will receive a free “Straw Hat Crew” shopper bag, while supplies last.
