Plucking all the way. Much cheaper than waxing, and you can do it sooner than you can re-wax (if you follow the rules about letting it grow in to such n such a length)
It is painful the first couple times but after that, you get used to it. I can (well, could, haven't done it since I got to france, why bother when I'm the only one seeing it?) do mine in 30min to an hour. When I get down to the labia, or however far I can before it gets toooo sensitive, I stop and shave the rest. Lasts a couple weeks. Just DON'T dig the hard to get ones. They'll grow out eventually.
Now what I would like to know, is how the heck do you get the stuff that's so far down you can't see it? I can get my labia farely well, but I can never get the rest baby-smooth.
