I am halfway through the vampire questline and would like to change my character's appearance, but cannot because he is a vampire.

My question is: Can I cure myself, change my appearance, and then have Serana turn me after I complete the vampire questline?

I believe so.

Yes you can...I think, I know that harkons turns you at first and it says somewhere on the uesp, that serana can offer it anytime after the soul cairn part.

Thanks for the quick answers.
