You can do the swoop and scoop to gather all the armpit and back fat into the bra cups you do need a good fitting bra though very tight in the band(wear a bandsize the same number as your underbust measurement) but slightly loose in the cups.
This is similar to chiyomilk others have had results with it too though including non biological female.
I think the bra is the most important part of fat brushing as even without the massage it can help gather more fatt to breasts.
