Did actresses have to stuff their bras for Two and a Half Men?

I watched the episode with Miley Cyrus, who actually has an A and suddenly had big breasts in the series.

Then I googled a few other actresses and they actually had much smaller breasts than portrayed in the series.

Did women really have to stuff their bras? And if so, what do you think about that? Do you think such facts have shaped the image of women and the idea of ​​beauty in any way?
