Multiway Bra

I'm wearing my bra with a low back dress I multiway bra, I have a picture with her lower back but I have no idea how to do it, someone could s If you please explain?? It would be greatly appreciated: D

the bra should have come with a long strap.

take the strap, clip it on one side of the back of the throat, wrap it around you (like your belly), and clip the other side of the throat. allowing you to shoot in the back of the bra.

You may need to loosen the straps of the bra too

Good luck!
