系統

• 読み: けいとう

• 発音: /keː.toː/

意味

Fashion category or style tribe; used to classify someone's overall look into a recognisable aesthetic type.

系統 in fashion slang refers to the broader category or 'lineage' of a person's style. Japanese fashion is famously tribal, and knowing someone's 系統 — whether it is カジュアル, きれいめ, ストリート, or ガーリー — helps shorthand their aesthetic. It is commonly used in fashion magazines, YouTube styling videos, and everyday conversation about what kind of look someone is going for.

例文

1. 自分の系統がまだ定まってなくて毎日違う服着てる。
2. この系統の服着たいけど、似合うかな？
3. 系統が違う友達と買い物行くと新しい発見があって楽しい。

正しい言い方

• どの系統のファッションが好き？ (What fashion category do you like?)
• 最近ストリート系統にハマってる。 (I've been into the street style category lately.)

避ける言い方

• 系統 is neutral — no particular misuse situations, but it sounds stiff in very casual slang-heavy conversation

よくある間違い

• Confusing 系統 with 系 (kei) alone — 系統 is the broader category while 系 is the suffix used in compound words like サブカル系 or ストリート系
