"Just don't stretch them out."
/I had this friend in high school who would sleep over at my house a lot. One time she left a pair of leggings in my room, and I mistook them for mine, so I wore them to school one day.
She saw me wearing them and asked if they were hers, and I realized that they were. I apologized, telling her she'd get them back. She told me it was okay, adding, "Just don't stretch them out."
I've always had bigger thighs. And I never used to care a whole lot. But now I hate them in every pair of leggings I put on.
