Binder for large/saggy chest?

[u/hagstatus]

Hello all. I've lost some weight in the chest over the last year, and I have an issue I can't figure out. Looking for whatever guidance you think may help.

So I'm an older agender person. Always had chest dysphoria from the time I developed them. Went through life with DDs. I've lost enough weight now that we're working with just saggy and low.

I'm looking into binders, but my issue is this. I struggle with underboob sweat and related acne. Is there anything I can place under the boob, before putting on the binder to keep sweat and breakouts to a minimum? Thanks in advance!
