Inspired by the seaweeds found along Ireland’s Atlantic coastline, this botanical study brings three distinctive coastal species together in a delicate natural-history inspired design. Irish Moss, Oarweed and Bladderwrack are individually illustrated and labelled, creating a quiet celebration of the plants that thrive along our shores.
Printed on soft organic cotton in Vintage White, the understated composition gives the tee a clean, easy-to-wear finish with a subtle connection to the Atlantic landscape.
