To celebrate its 35th anniversary, PINK HOUSE unveiled a collection born out of a collaboration with Momoiro Clover Z. On September 21, members of Momoiro Clover Z (hereafter referred to as Momoclo) held a fashion show wearing items from the brand at a pop-up venue held at Center Park/The Stage #2 on the second floor of the Isetan Shinjuku Main Building. Approximately 200 fans of Pink House and Momoclo packed the venue. The show began with "Overture," played just like the opening of a live concert, and the venue was filled with excitement as fans called out to them. Kanako Momota was the first to wear the look. She walked the runway in a look featuring her own color, red, and posed for the fans. Next, Shiori Tamai, Ayaka Sasaki, Momoka Ariyasu, and Reni Takagi each wore their own color, coloring the runway in five different colors.

Based on the pop-up's theme, "The boom comes from a sense of discomfort," the members also expressed a sense of "discomfort" through their styling. A complete departure from their usual adorable idol look, they adopted Pink House's signature soft, girly styling, paired with oversized collaboration varsity jackets for a rock and pop image. Their makeup also featured two shades of eyeshadow to create a striking look, while a dark lip color added a mature touch.

Online pre-orders for the limited edition, serially numbered varsity jackets began on September 22nd, but they were almost sold out within a day. Additional sales are currently under consideration.
