Undies do serve a purpose for some:
"They keep outer garments from being soiled by bodily secretions and discharges, shape the body, and provide support for parts of it."
Some people have other ideas:
- To protect "expensive" garments.
- To eliminate dreaded panty lines.
- To reveal your sexy side.
- So parents can yell at you to wear them.
- Visible panty lines. We need 'em. We really do.
- Aesthetics maybe?
What do you think?
