Printed pashminas are better. Summer versions with texture like Sylvie is describing are better too.
I have a thick, quilted black and silver brocade shawl that I use instead of a pashmina. It's a lot more rigid and geometric and does not drape. I prefer that look to a flowing scarf that acts like a shawl. I also have a retro shawl with sequins. It's like netting. It does not keep you warm, but it adds a dramatic period element to a dress.
