First, look away to respect her privacy. Then, in a calm voice, say something like 'Mom, I'm sorry. I didn't mean to intrude.' And then, give her space. If she wants to talk about it later, be open and honest about it, like explaining that you just happened to be there by accident and that you'll be more careful in the future.
Apologize sincerely. Try to have an open conversation with her about why you did it. Assure her it won't happen again and respect her privacy and belongings in the future. For example, you could say that you were just playing around and didn't mean any disrespect.
You might need to have a more in - depth conversation with your mom about privacy and respect. Let her know that you understand her feelings are hurt and that you'll respect her personal items from now on. Maybe she'll be more understanding if you show that you've learned your lesson. Try to focus on rebuilding her trust in you.
It can be really embarrassing. One option is to be honest and explain your reasons for wearing it, like if it's for a costume or just personal style exploration in a private way.
The consequences can vary. Firstly, it would likely lead to an immediate and awkward conversation. Mom might feel violated in a sense. Socially, if others found out, it could lead to rumors and a damaged reputation. And within the family, it could create a rift as it's not a normal or acceptable behavior.
You might explain that you were under a lot of stress and did something really out of character. Say that you didn't mean to disrespect her and it won't happen again. Also, admit that it was inappropriate and show genuine remorse.
