crowning glory(redirected from one's crowning glory)
1. Someone or something's greatest achievement. I've had some good ideas in the past, but this invention is definitely my crowning glory.
2. The best or most impressive part of something. The impressionism exhibit is our local art museum's crowning glory.
3. One's hair. It's amazing that she has maintained her crowning glory—her flowing auburn tresses are as beautiful as ever.
