Find some old glasses or movie theater glasses and punch out the lens (for both). If you naturally need and have glasses that's good.
Find a light brown or black eyeliner (the black goes best with blue or brown eyes). Put a thick line on at the bottom and a thin line at the top of your eyelid. This will make the glasses pop!
Find plaid or stripped shirt, pants, or skirt. Get black buckle shoes or stilettos. Wear a white or black blouse under your shirt.
Finish it off with a nice pink, purple, or bright colored bow(s).
