骨格診断

• Reading: こっかくしんだん
• Romaji: kokkaku shindan
• Kanji breakdown: 骨 (bone) + 格 (frame/build) + 診 (examine) + 断 (judge) → skeletal frame diagnosis
• Pronunciation: /kok.ka.kɯ ɕiɴ.daɴ/

Meaning

Body-frame typing that categorises people into skeletal types to determine the most flattering clothing styles.

骨格診断 is a fashion consultation system that classifies people into three main body-frame types: ストレート (straight), ウェーブ (wave), and ナチュラル (natural). Each type has recommended clothing silhouettes, fabrics, and accessories. It became enormously popular in the 2020s through social media and is now a mainstream topic in Japanese fashion. Many people identify themselves by their 骨格 type when shopping or asking for style advice.

Examples

1. 骨格診断やったらウェーブタイプだった。 I did the body-frame typing and got wave type.
2. 骨格診断に合った服選ぶとスタイルよく見えるよ。 If you choose clothes that match your body-frame type, you end up looking way better.
3. 最近骨格診断にハマってて、似合う服ばっかり買ってる。 I've been obsessed with body-frame typing lately and I've only been buying clothes that suit my type.

Usage Guide

Context: fashion, shopping, social media, personal styling

Tone: informative, practical

Do Say

• 骨格診断やったことある？結構当たるよ。 (Have you tried body-frame typing? It's pretty accurate.)
• 骨格ストレートだからVネックが似合うんだって。 (Since I'm a straight type, V-necks supposedly suit me.)

Don't Say

• 「骨格ウェーブだから太って見えるんだね」は禁句 (Saying 'you look heavier because you're wave-type' is taboo — 骨格診断 is about finding flattering styles, not criticising bodies)

Common Mistakes

• Taking 骨格診断 results as absolute rules rather than general guidelines — many stylists emphasize it is a starting point, not a strict system
