Many people consider them attractive, but not everyone has them – they are rather not visible. These dimples unanimously considered a sign of beauty are called the “Dimples of Venus” (“fossae lumbales laterales” – scientific name).
They are “created” by a ligament that connects the sacrum bone with the ilium bone. Their visibility is made by the joints that make this connection, and by genetics or body weight.
In conclusion, these two dimples are present on all people, but it depends on how pronounced they are on each of us.
However, they are better visible on thin people. On people with a few extra kilos, the Dimples of Venus are filled with fat and therefore not visible.
