Alfie x Underdays Capsule Collection
Where the effortless feminine meets the everyday luxury.
We partnered with Paris-based label luxury label ALFIE to create a limited edition capsule set of elevated summer essentials.
A collection with a “borrowed from the boys” feel, this launch celebrates ALFIE’s signature boxer shorts and Underdays’ solutions-driven design—all crafted from a luxury deadstock cotton sourced in Paris that is OEXO-TEX certified, meaning free from harmful chemicals.
Designed in Paris, made in Europe.
