意味

Oversized fit; deliberately wearing larger-than-normal clothing for a relaxed, trendy silhouette.

オーバーサイズ has been the dominant silhouette trend in Japanese fashion since the late 2010s. Oversized hoodies, T-shirts, blazers, and coats are worn by all genders, often styled to create a relaxed, effortless look. In Japanese fashion, the oversized trend aligns with concepts like ゆるコーデ (relaxed outfits) and こなれ感 (effortless chic). Brands specifically design items with intentionally oversized proportions, and knowing how to style オーバーサイズ without looking sloppy is considered a key fashion skill.
