She must go to a more non traditional church.. or non denominational church.. The church we go to I wear jeans, but I dress them up with heels and a nice shirt, but our services are more active and not jsut sitting there for two hours.. so If I was dressed up as if I were going to church like a baptist church I would probably be uncomfortable. Church should be more of a you wanna go type thing, not you have to do this or do that.. so when churches are not as strict people will want to go.. IMO, you could show up wearing rags and shoes with no soles, showing up is respect enough
