What does 'Red Star' mean in this context?
"I stand before you tonight in my Red Star chiffon evening gown."
This is what Margaret Thatcher said when she was a stateswoman in the UK.
What does red star refer to in her speech? The first letters of red and star were capitalized in all quotes I found.

Is there a significance funny enough that the crowd laugh loud?

Answer

It was a humourous observation. The dress which she was wearing at the time of her speech was a rather dark red chiffon.
The Red Star is a Communist symbol. So, she was likening the colour of her dress to the Red Star. Mrs. Thatcher was very much NOT a communist.
