Petite interview attire?

I totally understand. I'm 5'1 and 110 pounds. People still mistake my age for a lot younger than I actually am. But if i were you i would get some dress pants or the pants to a suit and get a cute blouse. I think if you did a neutral colored blouse and some black or gray pants then you could also use a pop of color in the shoes. Like a red shoe, cheetah print one, etc. Don't be afraid to be bold with the shoe because it really is chic. Good luck!
