I need some help.I will be visiting a local jewelry store asking them to make me a custom piece of jewelry, which will result in a fake lip piercing.Now the thing is I'm buying this as a gift for my girlfriend and I do want this to be a surprise.So I was wondering if I could get some tips on what to order?Since I've read online that the size,shape and thickness of the piercing has to be just right.Do you guys have any tips for me?
