Most people in the hospital that I've seen walking around wear standard blue scrubs. You won't get any free scrubs first year, but you can buy used anatomy scrubs (washed) from the second years for either $5 or $10 a pair. I would not suggest going out and buying nice new UVA embroidered scrubs for anatomy because they will get disgustingly covered in cadaver juices and you will not want to ever wear them outside of anatomy lab.
