Bridal shower decorations

I am having my bridal shower in the beginning of September and need some ideas! I don't have a 'theme' but I just want to keep the classic and gold vibe from my venue space (picture below) We were thinking of having floral arrangements on the table with burgundy and peach (my other wedding colors) and greenery in short gold vases. Planning on renting chargers and runners too. Other than that I have no idea what else to do! I am seeing all over social media these crazy balloon arches and flower back drops for pictures (Im looking into renting this but really just comes down to price). I want my bridal shower to be beautiful but not over the top like a wedding but not too low key like a business meeting. Does anyone else have ideas or suggestions? When I look at Michaels, hobby lobby and etc. I feel like a lot of that is for home showers.
