Cartilage piercing question.

lovepink42
so I got a cartilage piercing near Christmas, it's a ear/helix piercing, in around a month I can change the earring to another post earring but I'm a little confused about post sizing...

i got it done at Claire's and I'm pretty sure they use a standard 18g...but most of the earrings I've seen, I think even the ones at Claire's start at 16g...

I don't want to stretch my ear, are 16g OK to wear? I figured since it's pretty much the only size available it would be ok...but I just want to double check. and would I still be able to wear the original earrings I got it pierced with after switching to 16g?

any advice would be appreciated,

thanks!
