Gum Salon located in Milan used quite a few traditional elements but have created a really modern feel through the monochromatic colour scheme. The black tile, painted brick and Hollywood dressing room style lighting are all very simple but come together beautifully.
Their logo is great and they use it to good effect on the printed material and even their towels, which I love. A collection of antique cutting tools is incredible and really adds a great look to the space.
