Women Who Wear Beads, Small Ones, On Their Waist: Who Are They?

I have seen this thing on two different women.

First woman was doing exercise in her shop and was doing it in a way that makes the beads obvious. The place is a GRA but their house has a shop where they sell.

Second one, I was flirting with one and before I knew it, she's bent sideways answering calls.

The beads are like four or five.

I don't know what to make of it.
