When people say a new style is “not you,” they usually mean “not who I’m used to.”

People hold a picture of you in their heads, and that picture is built for their convenience rather than yours. When something new arrives, the discomfort they feel is about their picture needing an update, not about your taste. They are reporting surprise and calling it judgement.

Hear the comment as news about them, and keep wearing the thing for a fortnight. If you still like it then, it is yours. If you do not, drop it because you decided, not because somebody flinched.
