1968 was a year of passionate fight for equal rights. These ideals also reached fashion and design. Textile designer Annika Rimala, who was also a supporter of anonymous design, created the pattern Tasaraita (Constant Stripe) for Marimekko the same year.

A t-shirt with Tasaraita pattern soon became a symbol of equal rights, a t-shirt worn by men and women. Tasaraita also became the first tricot collection of Marimekko. The pattern is still in production and is one of the most loved ones of Marimekko’s classic patterns.

Tasaraita collection of today includes several shirts, dresses, trousers, skirts and night wear. The pattern is made in classic colours, but also in colours of the season, changed four times a year. Currently there are more than 40 colour combinations.

Cotton knit of Tasaraita been has been given an environment certificate Öko-Tex Standard 100. More than 14 million pieces of Tasaraita clothes has been sold in the world during the past 40 years.

Annika Rimala designed patterns and clothes for Marimekko in 1960–82. In 1967 she was chosen as one of the ten most influential designers in the world, who have affected fashion.
