The maximalist approach of STRIPES?
Horizontal and vertical lines in one outfit may be challenging, but I had to try it and I must admit it that I liked it. A colorful necklace and the red vintage bag are the only burst of color in this monochrome and graphic look. I hope I didn't cross the line :)
