I listened to one of Podcast programs that was about dress code. Dress cord is the rules for what you should wear in a certain situation. For instance, if a restaurant has a no-jeans policy or dress code, it means you have to wear smart trousers. You are not allowed in if you wear jeans. And I found there is a dress code called "Smart casual" and I had no idea what it was. It is a little difficult for me as a Japanese to understand dress code.
This category demands a pulled-together, harmonious, complete look with colors, fabrics, shoes, and accessories, for both men and women. ってことだそうなので、男女共通して言えるのは、「きちんとおしゃれしているように見えるかどうか」みたい。靴や服の素材感、アクセサリーをふくめ、全体的な色合いやデザインなどなどがきちんと調和していることが大事のようです。ただフォーマルドレスとかきちんとしすぎたものを着ていたらちょっと浮きそうです^^;) 海外ではドレスコードに気を使いますね。
