Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh

 

It seems to me that you are suffering from some inferiority complex. Somehow you hate to wear hijab; you should ask yourself: why do you think that way? If you love Allah and know that it is what Allah wants you to do, then you should be able to do it without any external pressure.

 

So, I would advise you not to do it for your father or anyone else. Instead, you should choose to do it for the sole reason of pleasing Allah: Your creator.

Having said this, I would also rush to point out: wearing abayah is not an essential requirement of modest Islamic dress code for women. You may wear any loose-fitting clothes that fulfill the requirements. For details, you may access the answer linked below:

Almighty Allah knows best.
