OCCASION is a line of RAGEBLUE, a Japanese casual fashion brand operated by Adastria. In the brand reorganization in fall 2025, it was positioned as one of three pillars alongside “TREND” and “STANDARD.” For adults who favor casual fashion, it presents functional suit sets as formal wear that can be worn in a variety of everyday situations. The first project was announced in August 2025 as a collaboration with “phenix outdoor.” RAGEBLUE as a whole offers a daily standard style that blends American casual and European traditional influences.
