In addition to traditional jewelry such as necklaces, earrings, rings, bracelets and anklets, what fascinates me most is the belly button ring. Although there are many non-traditional jewelry pieces that can be worn on various parts of the body (actually, I think most of them should be called rebellious jewelry, because they are mostly worn by teenagers with rebellious personalities), such as eyebrow rings, tongue rings, nose rings, etc., the vast majority of them make people feel uncomfortable and creepy. Only the belly button ring is the sexiest and most alluring. Of course, a flat stomach and a slim waist are essential conditions for wearing a belly button ring.
