How to decorate

I think some greenery and/or flowers will be pretty decorations for this venue!

Gorgeous! I would use LED candles as centerpieces and wrap clear Christmas lights around the pillars and ceiling.

I think it’s definitely possible to make a barn venue more classy/posh/upscale, as opposed to rustic. Draping, string/bistro lights, and uplighting can really transform a room. And choosing upscale table decor (avoiding all things rustic!) can have a big impact also - like alternative colored linens, instead of the standard white. Upgraded chairs, instead of wood. Elegant chargers & flowers (avoiding the typical flowers used at rustic weddings).
I found these images of more upscale barn weddings on Pinterest. Maybe they can provide some inspiration.

I would definitely add some vines & twinkle lights.

I recommend drapes and a lot of greenery.

I just want to say that your venue is very beautiful!!
