Purple: the uniform of the over-50 set.
Glad to hear you had a nice birthday.
I did see you mention it somewhere else so my official congratulations is there. Somewhere.
BTW, don't know if you have heard of The Red Hat Society
. It appears that some members will be descending on London for the New Year's holiday week. It's a (usually) purely social group for women, originally for those 50 and over, but now it's open to women of all ages. When going out to events, all members wear purple clothing and red hats.
