I bought this for my daughter, but as the material was so cheap & nasty she did not wear it. I passed it to a local charity shop unworn.
The skirt is shapeless with minimal elastic at the waist. The top a baggy mess.
Due to lack of time, we did use the wig. It was a little auburn, but did the job.
On the plus side, the glasses were better than expected. They are darker than the ones shown with thicker frames, which worked better for the nerd look.
Buy this if you want to sweat, itch and look cheap!
