I said, "you need either a binder or a better binder."
I found a binder that worked for me, suggested you also try T-Kingdom because my 36DDD's were damn near invisible. Between the binder and some strategic layers, you couldn't see them unless you were looking. And no, I didn't have magical boobs that laid flat- I had fibrous monsters.
I don't sugar coat either IRL or on the internets. You asked for an opinion, I gave you a polite one. Hell, i even gave you a CENSORED opinion.
