That's why my daily outfit is yoga pants. If I were in the Southwest, I'd probably switch to simple cotton dresses. One year there was a sale at Bass and I bought 3 of the exact same dress: like a polo shirt with a collar and short sleeves, only a dress. It was a great comfortable, casual look. Wore a different color every day.
As you can see, I tend to go for "uniforms." I don't like making decisions about what I'm going to wear every day. No wonder I wanted to be a nun when I was young--the kind with the habits.
