Well that depends on the person who's wearing the piercing. Both piercings if done correctly will look stunning on most women, it's what you want to say about "you" that matters, not the piercing. So talk it over with your friends and have a discussion with your piercer then decide from there.
I believe she has two lobe piercings in her right ear and two in her left, and one helix piercing in her left too. She has a nose piercing on her right nostril and a navel piercing.
Non piercing navel rings, or "clip ons" can be purchased and any jewelry store that sells standard navel jewelry. You can also find a large selection on Amazon, Ebay, Bellybing, and Clipbitz.
I would suggest going to the emergency room for medical assistance, if you mean a "navel piercing" then follow the written aftercare instructions provided to you by your professional body piercer. FYI no one does "Belly Piercing", if you find a place that does "Belly Piercing" that's not the place to get your "navel piercing" from. Seriously
yes she does have a cartilage piercing on one ear she also has a nose piercing and a belly piercing too.
no but she has one on her nose
it means to have a belly button (navel) piercing, whether its to have on or to get one done
A nose piercing can usually be changed after one week of having it pierced. You can try out places like Piercing Pagoda, Claire's, or even Hot Topics to find a nose piercing - depending on your friend's style.
One of two reasons. One, either the jewelry that you are trying to put in is a bigger gauge than the jewelry that it was originally done in, or the hole is closed either slightly to all the way, and you will not be able to get it back in without either shoehorning it in with a taper or waiting for it to heal, and then get it repierced.
a hollow needle. Pretty much what you see in hospitals and such. The size depends on whichever one you ask for.
No, it is actually one of the recommended aftercare treatments.
one to three months
It is possible, but actually rare. Even people that dont have a very defined navel "lip" can still get a navel piercing; it is what you call getting a shallow piercing, meaning there is not much skin to pierce through. I have seen successful healing with shallow piercings, and I have also seen some that are not so successful. Talk to your piercer about whether or not it is a good idea for you to get one.
