Sometimes a client asks me why her bra slips down her body during the day. She puts it on in the morning so that the wires are flush with the root of her breast but it still manages to wiggle its way down her body. There are 3 main causes for bras that slip down the body:
Wire Shape
If you have a wide breast root and you're wearing a bra that has narrow cups (like Gem in the picture above) then it's like trying to keep a tennis ball in an egg cup. You might be able to squeeze the tennis ball into the egg cup but the pressure is going to build and the tennis ball will pop up.

Torso Shape
I've written a lot about torso shape because for some women this is the biggest shape factor that affects their bra fit. If you have a flared torso that is wider at the top of your band than it is at the bottom then you can often find that your bras slip down.
Lots of my clients with flared ribcages wear their bands on the loosest hook at the top of their band and the tightest hooks at the bottom to offset the size difference. There's no easy fit fix for a significantly flared torso but bra extenders can help you create a wide fit at the top of your band and a tight fit at the bottom.

Cup Size
Similar to the tennis ball in an egg cup scenario, cups that are too small for you cause a pressure build up and eventually your breast tissue wiggles out of the cups and forces the bra down. Your bra wire should go all the way around the outside edge of your breasts without spilling over the front, sides, armpits or beneath the band.
