Catherines Plus Size Store What Color Pantyhose Should I Wear To This Job Interview?

What color pantyhose should I wear to this job interview? - catherines plus size store

I have an interview with Catherine Plus Size Clothing Shop today at 4 clock, and I'm using a pencil dress which is black on the bottom and gray and white above. I also use low black heels with him. I'm not sure if I wear black tights or transparent. I am very pale and so are tights ..

What color would look more presentable?
So, I'm 18 if that matters at all, which would be more appropriate.
Thank you!
