Hey girls, going to work with a sprained ankle

Hi I have a question for the girls. Two days ago I severly sprained my ankle. I'm in an aircast stirrup and on crutches for at least two weeks. I'm going back to work tomorrow and I work in an office. I have a few pantsuits I'm going to wear. I'm going to wear a sock under the stirrup and no shoe as that is what my doctor said to do. A few questions. Have any of you girls ever been in this situation? I have mostly athletic socks but would like to keep it cute so if you did this do you think I should wear maybe a knee high ? Or just go with the ugly white sock? Just wondering your expirences? Also was it ok to keep your foot on a chair with a small pillow under it? Gonna be fun keeping that foot of the ground at all times! Suggestions and expirences please!! Thanks girls.
