I've observed that when it comes to navels of American celebrities, a few names get regularly called out such as Victoria Justice, Taylor Swift and Millie Bobby Brown. While I get how Victoria's and Taylor's innies got popular (unsure of how Millie's got so many fans), this got me wondering- how do fetishists zero in on them?

I mean if navel exposure was a criteria then Shakira or JLo should've gotten a fanbase way larger than Victoria and TS. Ofc, this is a trend you might observe in other countries as well, not just the USA, where celebrities are associated with a certain part of their body more often than not.

As far as navels are concerned, I'm not sure how some women standout from the others. What's the X-factor here?
