how are you going to cover the change in wardrobe?

I was just going to take a page from Lucas's book and have them do like Padme and change cloths every 5 minutes.

Actually:

For Han I was going to try to stretched his A New Hope shots as much as I can for the battle (might not work) so he'd be in his vest the whole movie.

Leia would only switch to her Hoth gear after they land and would continue to where it while they're are running away. When she gets the the end and helps corrodinate the battle, back to the white dress and donuts in her hair.

Luke would be wearing his white tunic until Hoth, then his wardrobe change would follow with the rest of Empire until he goes to Coruscant/Emperor's Palace/Cloud City. Then sometime after getting taken by Vader but before arriving at the Emperors throne room, he'd switch to his black outfit. I thought it might be fitting that Vader might have given him a Sith wardrobe seeing as how he is taking him to the Emperor to be turned.
