Etw. Vonneguet, led by designer Olga, presented their Spring/Summer 2013 collection at the Shinjuku Washington Hotel. Under the theme "I melt," the collection incorporated the image of melting into clothing. The collection alternated between men's and women's styles. Most of the looks featured silk fabrics with gradient prints of yellow, blue, and green blending together, as well as jersey T-shirts. The hems of the T-shirts were dissolved with chemicals to create a drape. Bottoms included pants with colored inner thigh panels, loose cropped pants, and gradient colored tights, creating a street-style feel. The final look featured a model clad in water-soluble nonwoven fabric, which was sprayed with colored water and melted in front of the audience. Olga explained, "Until now, I've never made showpieces because I thought they were pointless. However, I thought it would be meaningful to present something that disappears in a show, so I created dissolving clothing." Regarding the theme, he said, "There are times when I wish I could just disappear. That's where the idea came from. With the cooperation of Okuda Dyeing Factory, I focused on creating a melting look for the textile."
