Do the couples get to choose? Some have a much better second dance which they have focused on so you'd hope so or else it might be unfair...

Just a thought.

It always used to be your best dance of the two, based on the judges' scores. (Or, presumably, couple's choice if both dances scored the same.)

You'll be able to tell when they line up for the eliminations on Sunday night, as they'll all be dressed ready for whatever dance they'll be doing *if* they are in the dance-off.
