Does it secretly bother you when you know a person who is always well dressed and put together?

I always admire people with style. I passed a "woman of a certain age" yesterday on a beautiful day: she was attired in a lilac-patterned ankle-length dress with matching accessories and a wide-brimmed hat.
I stopped her and said: "Excuse me, Ma'am, you look so elegant!". In return I received a beaming smile, and a "Thank you!".
Compliments cost nothing.
