What to wear?!

Thanks for the replies everyone

i think im going to go with a blouse and slacks! going to the mall soon

I look really young, but i just turned 21, im sure they are going to be a bit suprised when they see me. Usually everyone when they see me, they think im still in high school LOL.. so when they see im a nurse and i've been a nurse for a almost 2 years they are pretty impressed.. so hopefully they like me and aren't looking for someone a bit more seasoned.
