The word 'Hat'

Last week I was asked to take part in a ladies luncheon charity event. They asked me to speak about how I began Rosie Olivia Millinery, why I am so passionate about making designer hats and how I would like to expand the business.
We discussed how many meanings the word ‘hat’ has!! I thought I would share.....
At the drop of a hat - immediately
Keep it under your hat - keep a secret
Old hat - old fashioned
To talk through one’s hat - to talks foolishly
Eat ones hat - shocked or proved wrong
But of course if you would a designer hat ...... then please contact me
