The Erna t-shirt is made of organic cotton jersey, and it has a relaxed fit. The t-shirt features the small printed Lempi Unikko pattern flower in the front. The t-shirt has a ribbed O-neck.

Unikko was created by Maija Isola in 1964 and has since become an international icon of print design. The founder of Marimekko, Armi Ratia, believed that it was not possible to faithfully capture the true essence of real flowers in print, which is why floral prints were earlier excluded from Marimekko collections. So, Maija Isola designed Unikko to be an abstraction of a flower rather than a photorealistic rendition. Today, Unikko is a powerful emblem of joy and creativity, seamlessly integrated into Marimekko´s design identity.
