Dancing with a tail?

So my gown has a huge long tail, and I do have the choice of a smaller white gown that I can change into before we dance.
Has anyone danced with a long tail before? (if so how?)
Or should I just change to the second dress?
I'd love some experience shared or ideas on this. Thanks. =)

you can pick up your train, its called a bustle. Any alterations place can do it for you.. this way your train wont drag and you can dance freely

I had a second dress for the wedding but didn't end up using it as I really loved wearing my dress. I had a bustle (PIB) and it worked perfectly. I would not recommend trying to dance with the train unbustled - people will step on it and you will tear your dress.
