Didn’t Carrie Fisher say in an interview that Lucas said she couldn’t wear a bra because they don’t have bras in space?

She didn’t seem to be particularly pissed about it. I assume he had cinematographic reasons and made the comment in jest. Heck if it weren’t for people talking about it I would never have noticed, certainly didn’t notice as a teenage horndog which is saying something.

Why not make Anakin shirtless?

I’ll just leave this here. I only googled the scene the internet did the rest, don’t shoot the messenger.
