Less 2017 autumn and winter series. July, suddenly and this fall. The climax and the end of the summer rushed in and disappeared in June. Like Cadenza, it was only after a high tide that the high tide went down. The "not pure but charming" screaming about the whole season has finally come to an end. In the beginning of autumn and winter, rational emotions as a lasting internal driving force are still emphasized by less. This season, we walked back to a minimalist and detailed design style, showing a simple and simple resilience. Some willfulness is bravely persisting in the long run. Some toughness is the lasting force needed to walk the world. This season, I hope you and I can precipitate themselves in imperfections.
