Long skirts.

Love the long skirt. I'm tall, so it makes me feel tall in an elegant way, not a galumphing way.  Suitable for many seasons, if you layer properly. Actually works super well in the rain because the skirt can get wet, but it isn't touching you so your legs or leggings stay dry underneath.

I flicked through an illustrated book I own called When wanderers cease to Roam and on this page the author observed that the Muslim women in Niger "moved like mermaids" in their long wrap dresses, and so she started wearing long dresses too and observes that modesty is more relaxing because you don't have to hold your stomach in.
