Am I wrong 🙄😂

My first cousin is having a lingerie party and I was under the impression that it was all women. So I was all in! I went shopping for my lingerie outfit and robe to go over it. I kind of thought it was weird to be dressed in lingerie in front of a bunch of women but ya know it’s the new trend (I guess). But now I found out that she’s invited guys so I backed out. First of all I’m newly married and I have never even wore lingerie for my own husband so why would I walk around in front of stranger men in a hotel in lingerie...... So I told her I’d come under one condition. I’d come if I can wear regular street clothes!!! So she flipped out and what not and told me I’d ruin the whole mood if I wear street clothes, etc. She is like super pissed and said I’m dramatic and do the most and that it’s not even that serious. Am I wrong?!??
