She replied that it doesn’t matter what I say because she’s going to wear what she wants anyways. I think that’s completely fair and it’s also fair for me to express my opinion. She’s good to reply how she did but do either of us seem disrespectful in any way? Second opinion to see if I’m toxic

The other small thing is she has nip slips sometimes and I asked her if she liked them. She said she doesn’t like them but doesn’t dislike them and mentioned she doesn’t see boobs and nipples as sexual. I don’t feel insecure but it feels a bit inappropriate. I wouldn’t care to comment on clothing usually but I do find it in poor taste if they’re so high you can actually see cheeks or if she’s fine with other guys seeing her nipples while in a relationship. It makes me a bit sad because I saw that extent as special to a relationship.

Is it typically to feel this way on nip slips like that and a bum or am I being toxic? This is my first serious relationship and i want to get another opinion on if im having unhealthy opinions because i really like this girl
