Trans tape Versus Binder (Long work hours)

Hello. I started working a 12 hour shifts, I know the binder rules (I cannot go against them I already have some breathing issues, nothing major but I'm not pushing it). I have never worn tape, as I have G cups, on a slimmer frame so they are apparent I understand I will never be fully flat but something is better than nothing. Can anyone give me advice on their experiences and tutorials for large chests?
