Size: 37-39 The Kasvaa ankle socks are made of a cotton blend and they feature the Tasaraita (even stripe) pattern with the poppy flower of the classic Unikko pattern. When jeans started to become increasingly popular among both women and men, Annika Rimala wanted to design a collection of cotton jersey clothes to go with jeans. For all denim lovers, regardless of age, size or gender. Thats how Marimekkos first cotton jersey collection was born. Evenly striped, expressing equality. Marimekko´s famous poppy pattern Unikko was born in 1964 in a time when the design house´s collections featured mostly abstract prints. Designer Maija Isola wanted to create something interesting from this organic theme and designed an entire range of floral prints. Today, the iconic flower represents creativity.
