You’re going for femme? Not sure how nice the church you’re going to is, and what the norms are, but here are some ideas.

You could go with a button down shirt and fitted leather pants. (A leather pencil skirt with some tights would look great too!)

You could play with textures and the like. Silk, eyelets, frills, damask… You can get some interesting looks with layering.

You could do a blazer, jeans, and a nicer T-shirt. Make sure these are all decent quality. I would only go with this if the church is ok with more casual wear.

You could wear a jacket with patches or pins. Again, I would only do this if you’re comfortable going in something more casual.

Don’t forget what you can do with your hair and accessories. Will you carry a purse? What jewelry? How about the shoes? (Combat boots with a more femme outfit would be adorable and can read pretty queer.) Will you want to wear makeup, and what kind of look will you go with if so?

One thing I really feel like makes people look more put together is making sure that the colors harmonize with each other and your own coloring. So if you’re warmer toned, stick with warm tones.

I don’t know anything about your style. If you’re stuck, I would start with an outfit you like (or an outfit you wish you could wear but never had the occasion to). Take a look at it and edit from there. You might want to balance femme with a touch of masc. You might want to find a nicer version of one of the items. You might want to find a more flamboyant version of one of the items.

Last but not least, make sure you feel like you. The best queer fashion comes from people that are confident in what they’re wearing!
