As an at least DD (haven’t precisely measured in a while) it is ABSOLUTELY easiest and often most effective on a small chest and I BURN with jealousy every time I see someone only needing two total pieces of tape to make it work well. But, I have also seen it work well on larger chests so I want to see if that can be the case for me or not. Hope to god I can eventually make it work, being able to keep my chest bound for multiple days at a time instead of needing breaks sounds like a dream
