Westover says this about her roommate because the girl dresses in a way that is inappropriate for the Mormons Westover grew up with.
We can arrive at this answer because:
- Westover grew up in a very conservative Mormon community.
- She didn't have access to anything at all and didn't know how the world worked.
- She was taught that women who show their shoulders, wear fair and popular clothes are immoral women and that they do not correspond to the way a Mormon woman should dress.
When Westover goes to college, her roommate dresses exactly that way, but the girl is a Mormon, which leaves Westover surprised, as the girl doesn't dress or behave the way she was taught.
This question is about the book "Educated" written by Westover.
