Here in Texas you could find a UPC church that is exactly what you are looking for. Strictly 3 stepper but with pretty relaxed standards on dress and media. Or an independent oneness church with UPC roots like Grace Church in Humble comes to mind. The hard line old timers always like to say that as soon as a church relaxes it standards they stop preaching repentance, Jesus name baptism and HG infilling but it's just not true.
I personally am a three stepper if I had to say but see how people have come to other conclusions. I still wear dresses only pretty much because I love them and own a bunch. I don't have any trouble hunting, fishing, hiking, biking, riding a horse, etc in a skirt. I can't run due to a plate in my ankle but i walk at the local HS track with a bunch of ladies from the local OP church and we all wear skirts and several of the girls from my former UPC church do marathons in skirts. I love how they hide my huge rear end the way pants never could
I don't enjoy secular music much and listen to gospel and contemporary Christian music mostly but I'm not offended by secular music that is not trying to be offensive (some is). I drink wine but don't get drunk. I use whatever language is appropriate to the situation believing that what is a 'cuss' word is decided by the time and place... I don't 'curse' anyone ever and try not to be offensive with my language, but alas have failed a time or two with those constantly looking to be offended.
I don't own a TV. Many of my more educated secular friends including a lesbian doctor don't either, so I don't see a lack of TV as any kind of 'holiness' statement. It is just a mind numbing retard box I don't need sucking up the time I have to get other stuff done. I watch interesting stuff on the internet and occasionally (very) go to movies which I just see as a bad bargain... lot of money for little entertainment.
Of course I don't currently 'go' to church anywhere and that seems to be suiting me better then I ever believed it would so maybe my opinions shouldn't count
