As-salamu alaykum - How can I get my family to allow me to wear loose pants?

As-salamu alaykum. I’ve been raised to believe that women wearing pants is sinful no matter how loose they are. My family says even loose pants are worse than skirts, and they won’t let me wear them in front of female relatives outside the home or around children. For the longest time I accepted that, but as I grew up I started seeing Muslim women wearing baggy or loose pants and wondered if it was really haram. I asked my Islam teacher and he told me loose, non-transparent, non-tight pants are permissible for women - it’s not Islam forbidding them, it’s my family’s culture. When I tried to bring this up, my family reacted angrily and insultingly, even suggesting I remove my hijab or change myself to suit them. I don’t mind wearing skirts or dresses sometimes, but I’m worried about wearing them every day because they draw attention. My mum complained that an acrylic ring was attracting stares and said that every look is a sin, but skirts here are actually more noticeable. Where I live almost everyone wears pants, so skirts make me stick out, and I get stared at by older men. For me loose pants are actually more modest: they hide my shape better, don’t blow up in the wind, and are more practical. My family’s views are tied up with a cultural mindset that prioritizes men’s opinions over religious guidance. They also scorn the hijab as “not our culture” and there’s a lot of prejudice against outsiders in my area. I’m planning to get a weekend job and thought about buying pants with my own earnings, since it’s my right to spend halal income as I wish, but I’m afraid of the fallout. I don’t know how to change their minds without causing big conflict. Has anyone here dealt with a strict, culturally driven family on this? How can I calmly explain the difference between culture and fiqh, and possibly get permission to wear modest, loose pants while keeping my family relations intact? JazakAllahu khayr for any advice.
