I have been commissioned to post this from a topic that was raised over on the S&S board. I see that The Mysterious H.C. has already responded over there, but I'm curious as to what some others of you have to say about this. Here is a portion of the original post from Karen B.:

I'm reading The Regency Companion these days, and I came across this, in the chapter "The Fashionable Lady": one of the rules of behavior a fashionable young lady had to follow was "Never express an urge to be wearing a warm pelisse or shawl. The very lightest of wraps should suffice in every type of weather."

Now, was this tenet more than likely followed only by the highly fashionable, as The Mysterious H.C. has suggested? What would be the reason behind this kind of ridiculous notion?
