London-based Studio Swine has produced a set of gold and silver clip-on buttons inspired by the textures and shapes of modernist architecture (+ movie).
Studio Swine designed the accessories to clip over standard shirt buttons so they're easy to transfer to different outfits.
"We felt that men's accessories were quite limited," the studio told Dezeen. "We wanted to create some that are accessible and make it easy to customise your clothes into a special piece."
The seven designs are largely based on patterns of modernist concrete buildings, like the ones in São Paulo that feature in the movie above. "We wanted to make buttons that would carry tactile information; wearable architecture."
Shapes include a perforated gem, square gem, cloud, triangle, factory, star and special-edition pixel.
Ranging from seven to twelve millimetres in diameter, the hand-finished buttons are available in 18-carat gold or silver plate.
They have recently launched on crowd-funding website Kickstarter.
Our last story about Studio Swine featured a movie about an open source chair made from plastic salvaged from the sea.
