What's missing in this picture?
Not clothes, sir, but this:
A belly button.
Underwear model Karolina Kurkova has no belly button. Is a barely-there navel for cosmetic or medical reasons?
The newspapers call it the "riddle of the £2.5m beauty". The beauty in question is Czech supermodel Karolina Kurkova. The riddle is her non-existent belly button.
Its absence was noticed this week when the 24-year-old graced a US catwalk for lingerie giant Victoria Secret. While most of us have an "outie" or an "innie", Ms Kurkova has a smooth indentation (although sometimes a tummy button is airbrushed onto her photos in post-production).
Yet another sign of our arrival in the post-human age.
