is my dad acting inappropriately?

he keeps getting mad at me for wearing 'revealing' clothing (e.g low cut tops, crop tops, short skirts, bikinis) at home but won't tell me why he doesn't like it. he comments on my body a lot and says that my boobs are too big for the things i'm wearing and has to physically cover his eyes when i'm near him sometimes so he doesn't stare. it makes me really uncomfortable when i can feel him staring at me and it feels sexual when all i want is to wear what i like in hot weather. my mum gets mad at him for saying things too me but he doesn't seem to care or listen to her about it. am i overreacting? should i just wear different clothes?

you wearing low cut tops and dressing provocatively probably makes him feel uncomfortable.

i'd probably not like it too if my sister was always wearing that and i had to be round her..

Yes.
It sounds like your father is in the habit of making unpleasant and inappropriate remarks at home about your clothes.

To avoid experiencing any more of his rhetoric and negative attitude, consider avoiding him.
Particularly try to ensure that you stay out of his sight whenever you are wearing anything that could trigger another verbal outburst from him.
Plus try your best to save up enough money to finance moving into your own accomodation as soon as possible.
So that you can wear whatever clothes you like at home without being hassled, insulted or emotionally blackmailed.
I understand some of what you are feeling, I got almost constant hassle from most of my mother's toxic pals and violence from my mother for ignoring their demands.
Good luck!

At first I thought that maybe he was still in denial about his daughter becoming mature (I guess it would feel weird for a parent to think their child is going out into the bog bad world on their own)

But the fact that his staring seems sexual is concerning
No father should behave in such a manner
Talk to your.mother about this
Has anyone else noticed this behaviour ?

why should it make him uncomfortable though? why is he seeing me in a sexual way? it’s weird

Would you be uncomfortable if he got his **** out? Is that because you "see him in a sexual way"?

Idk why men always think getting their **** out is equivalent to a women showing breasts, or even just a revealing top

It's not the same. The same would be a women walking around with no underwear on. It's really that simple.

I do think wearing bikinis around the house is a bit much tbh I know it's been hot recently but it's just as easy to wear some shorts and a tank top or whatever. I guess if you consider that a bikini is essentially wearing underwear I'm sure most fathers would feel uncomfortable seeing their daughters like that.

But still, I don't see the problem with wearing crop tops or short skirts and the fact that he has to cover his eyes so he doesn't look at your breasts is just creepy. He shouldn't even be commenting on your breasts or any aspect of your body. He's gross.

This definitely needs more context. But nonetheless, no, his behavior is not appropriate. It's not particularly nice either. Has this been happening for a long time?

I'm just curious though. Do you have any other siblings? How does he act towards them? Are they both your biological parents? How does your mother dress? How did you used to dress in the past during the summer? How old is he? Did you parents ever have problems with one cheating on the other?

If you're purely dressing the way you are, because it is hot and it is summer... then there is very little wrong with it. If you are dressing the way you are as a means of seeking attention, then perhaps you should think harder about this. But somehow, I really doubt you would be doing that in your own home, around your parents of all people. That's just... not normally how it goes.

It sounds a lot more like he is the one with issues. He may be anxious about you maturing and dressing too revealing around other people. That's normal for a lot of parents. But staring at your boobs isn't.

I've never been in a remotely similar situation, but to have someone you've known for this long act that way towards you... yeah, no. I don't think this is right.
