I cant have a navel piercing because my body always rejects them.  I either stay infected or the skin that hold the belly ring in place just gets thinner and thinner until it falls out!  That happens whether they are surgical steel, titanium, or bio plastic, all of which are supposedly hypoallergenic.  After 3 failed piercings, my navel was ugly from infection and the skin rejecting it.  I had to have it surgically corrected.  Some of us just cant wear navel rings, so I was excited to see a product like this!  Alas, my belly button is tight because of the surgery, so I don't have that little overhanging flap of skin like they do in the pictures, so the ring wouldn't stay on me at all and looked totally fake.  Ladies, I found a much better solution to making my own!  I used an old dangle earring, with the hook removed.  I applied a few drops of eyelash glue to the top of the dangle and stuck that in my belly button, held it there for a minute while it dried.  Then, I took a matching color rhinestone (the kind you buy at a craft store) and glued that just barely above my belly button.  It stuck well for hours and hours and people thought it was real!  I really loved it.  Unfortunately, the eyelash glue didn't hold up when I went for a swim, but otherwise it did great.  It seemed to be fine with sweat, but just don't swim in it.  If you have a tight round belly button like I do, or if your missing that flap of skin at the top, you're better off trying something else!
