What is Formal Friday?

Formal Friday is a Helsinki menswear brand that applies technical thinking to everyday tailoring. Its collections cover suits, formal shirts, trousers, blazers and T-shirts, cut from performance oriented materials such as merino wool so that smart clothing stays comfortable through a working day.

History

The company was founded in spring 2014 by three people with complementary backgrounds: clothing designer Teemu Muurimäki, mechanical design engineer Pentti Jokinen and business graduate Toni Tervilä. Business professionals Tatu Artman and Lauri Mäkelä later joined the venture.
