Ok 1st of all I can only assume your husband and fathers reason is religious. The Bible does say that women shall not dress in mens appareal. Some take it literally others, interpret it into...guys don't wear skirts, women don't wear ties ect. My husband and his family are pentecostal.....if you know anything about that, the women wear skirts and dresses no if ands or buts about it. There is a nice saying : Hevean, don't miss it for the world" You haven't go to do it just because the other girls are. They probably just have your best interest in mind, as well as the Lords from their point of view.
Try this, You know those pants that have huge legs, so much so they look like a skirt? Ask about those. They are perfectly modest and very pretty, and look like a long skirt. Find skirts or dresses that MAKE YOU FEEL PRETTY. That is a key. Get shoes to go with your different skirts and dresses, and shirts. Accesorize, belts, jewlery, purses ect...dollar store is cheap and has way cute stuff! A woman no matter what she is wearing can still look and feel amazing. Remeber nobody else will know you aren't "allowed" to wear jeans. Just rock what you are in, and you will look and feel great! Besides skirts are way more feminine and I think they make a woman look gorgeous. There's something about a woman that doesn't have to show off in tight close and still look amazing! : )
