My favorite dress. I still love it, but...

This dress I've had since I was in middle school. I loved it so much I'd sometimes wear it in ways that might stretch it out? (Like putting my legs into it when sitting in a gym pose lol) My mom would occasionally say, 'I bought this back when I was in high school or college~☺ It was expensive, so please don't stretch it out! 😒' but when I asked how much it cost, she'd just say 'It was expensive!' and leave it at that. When I was in college and still wearing it because I loved it, she said, 'You've been wearing that for a long time~☺ Should I tell you the price now?' and finally told me. It was way more than I imagined, and I blurted out, 'Oh, should I... pay you back for it?' I wanted to know, but maybe I shouldn't have asked lolololol I can't put my legs into it anymore lololol
