Best material for a pelisse

[Issy]

I am having a pelisse made but I can't decide what type of material to have it made out of. I was thinking maybe wool, but I am worried that it will be too thick as I won't be wearing it during the winter, as there are never any regency events here then. Another option is a wool twill. Which would you recommend? Or is there another fabric which is better?

Thank you

What about a lightweight wool? That would be my choice as the tropical weight ones aren't as heavy & hot as wool coating.
