If its just a matter of turning the skirt around, and nothing will be exposed, I just do it.
This does remind me of me and my prom dress. It was strapless, and as I was a bit of a late bloomer, had very little to hold it up, so my mom actually had to take in the top. Undr which I wore a strapless bra. Which somehow, after a full night of dancing, ended up around my waist! Thankfully the dress was not see through, so I just let it be, rather than keep trying to pull it up.
