I think that certain facial piercings can suit some people, but look pretty bad on others. I could give you my personal opinion if I saw a picture of you. I don't think tongue or naval piercings are trashy if you don't act trashy. Its just that a lot of trashy people have tongue or naval piercings, so they get a bad rap. Personally, I think that simple steel barbells look nice in tongue and naval piercings and might be a less trashy alternative to acrylic ends with funky designs on them, or dangly things. I also think tongue piercings look better stretched to a 10 or 8, but again, that's just my personal preference. It's really your call though. Like Evangelina said, get a piercing for you, not for someone else.
Its your body, you do what you want with it. I've got a medusa in my top lip and a labret piercing in my bottom lip, and while I can't wear them for work, I've got to say I've had nothing but complements about my piercings.
