Thank you for your help. I am very petite and short. I wore a black suit with a turquoise turtle neck to my other interviews. The suit was couture and the smallest size, however, I still looked like I was wearing my mom's suit. So thats why I want to go with a navy skirt suit (I bought it in high school, but it still fits really well) and only wore it two times. And it is long, hits the knees, and one-two inch above when I sit. So I dont think there will be a problem with that.
I wanted to wear red, because the interview is in DC.. and thought that might be cute?!
So thanks for the input 🙂
