Activity for Shanel

I am looking for shapewear for my wedding dress but am having a difficult time since my back is open in two different sections. Any suggestions? I was told to just cut my shapewear for the bottom section. Has anyone tried this? Or any suggestions?

My fiance and I are performing a ceremony just the two of us in the city of San Fransisco, CA. We are looking for someone who can decorate our hotel room for our wedding night. Any suggestions?
