意味

Straight body-frame type in 骨格診断 (bone structure diagnosis); characterised by a defined, structured body with prominent joints.

骨スト is an abbreviation used in the hugely popular Japanese self-styling system 骨格診断 (skeletal diagnosis). People diagnosed as 骨スト (straight type) are said to have a body with defined muscles, prominent collarbones, and a structured silhouette. This type is advised to wear fitted, simple, high-quality pieces. The three-type system (ストレート, ウェーブ, ナチュラル) dominates Japanese fashion advice, with people using their type to guide all clothing and styling decisions.
