Product Info

Smartly subtle, scientifically inspired.
Bring Ernst Haeckel’s legendary marine illustrations to the beach with these Nudibranch High-Waisted Bikini Bottoms — available in four variations featuring your choice of delicately placed sea slug: Okenia elegans (yellowish), Ancula gibbosa (greenish), Facelina auriculata (reddish), or a minimalist solid white version with no stamp.

Each “Nudi” sits just forward of the right hip, giving a quiet nod to one of the ocean’s most enchanting oddities — the nudibranch. Derived from Haeckel’s 1899 Nudibranchia plate, these swim bottoms turn vintage science into sustainable, wearable art.

Made from certified recycled polyester sourced from post-consumer plastics, they provide UPF 50+ sun protection and soft, double-layered comfort for confident adventures by the sea or pool. Zig-zag stitching ensures long-lasting shape and stretch.

Pair them with the matching Nudibranch Bikini Top (sold separately) or mix and match for a custom look inspired by ocean biodiversity.

Why Made-to-Order is Better for the Planet 🌎

When you choose made-to-order products, you're making an eco-friendly choice that helps reduce waste and pollution. Traditional mass production results in millions of unsold garments ending up in landfills or being incinerated, releasing harmful toxins into the air.

By only producing items when they’re ordered, we eliminate excess inventory, reducing textile waste and lowering the environmental impact. Plus, this sustainable approach conserves resources by avoiding overproduction.

Your purchase supports a smarter, greener future—one where fashion is made responsibly and only when truly needed. Thank you for making a difference!

As every item is made specifically for you, we usually can't accept returns but if you have any issue with your item, contact us we will be happy to help in whatever way we can.
