I wanna get my nips done!

Julie
Hi all, 
I've been wanting to get my nipples done for a while now. But I've been putting it off since I'm so unsure of how they'll look. I'm 5'2 with 36DDD boobs and I feel like I have the worlds flattest nipples. I have many piercings and tattoos, so pain isn't a problem.
But has anyone ever gotten their nips done that are flat? They do become erect when cold or horny, but even then I feel like they're so small. 
Let me know.
