- Design: SMFK form-fitting fitness cardigan, combining dance training apparel with a fitness jacket design, featuring a large round neck. The sleeves adopt a motorcycle leather jacket silhouette, while the waist incorporates curved lines inspired by motorcycle and racing apparel, creating a structural line that distinguishes the front chest from the sides of the waist and abdomen, showcasing SMFK's minimalist design philosophy that structure is beauty. A cross logo is printed on the sleeve.
