SF1OG is a Berlin-based fashion label that blends Zeitgeist with historical inspirations to create today’s most current garments. Since its debut in the Autumn/Winter 2022 show, SF1OG has been a leader in promoting sustainability, gender inclusivity, and craftsmanship in the fashion industry. 


Founded by Rosa Marga Dahl during her fashion design studies, SF1OG is co-directed with Jacob Langemeyer, who manages the label. The name "SF1OG" stands for "Seitenflügel 1. Obergeschoss," the German term for "side wing first floor," reflecting the humble beginnings in Rosa's one-room flat.


The brand's product portfolio includes three distinct lines:

101 Line: One of a kind garments made from repurposed, often antique materials.

013 Line: Handmade garments crafted in Europe from either deadstock or responsibly sourced new materials.

133 Line: Accessories and jewelry.


SF1OG lately appeared in publications such as Vogue Runway, Office Magazine, 032c, Sleek, Fucking Young!, The Perfect Magazine, Numero, i-D Magazine, The Greatest, GQ Germany or Highsnobiety.


In October 2023, SF1OG was honored with the UGG Culture Changemaker Prize for its dedication to driving positive change in the fashion industry.
