^ Outer labia heal much slower than inner labia. Inners do heal very quickly. I think the best approach would be to find a really good, experienced piercer and get them done at a fairly large gauge, then stretch them slowly and gradually once they're fully healed and ready to stretch. I'm not really sure about how long you would wait between stretches and whatnot but your body will tell you what it's comfortable with. Good luck!
I have 1/2" lobes and 11 piercings: left helix x2, both conches, both nostrils, septum, navel, and VCH.
My lobes are small but I know a lot about stretching and how to do it safely, so message me if you have any questions!
