How do celebrities make sure you can't see their bra?

[carey:]]

Okay, I'm so sick of wondering this...
I know sometimes girls don't wear bras
but sometimes you can tell they definitely are, yet you can't see it!
I'm not talking about actually seeing it, but the outline of it.
& it looks like they're not even wearing undershirts, and their shirts are thin
so how can they make it so you can't see it from the back, especially when you hunch over?
Mine's always showing no matter how much I layer!
Help please?!

there are special bras that they make for specific outfits.
like not just strapless and theres like boob suction cups and things like that

most female celebs either wear strapless bras or bras are actually fitted into the breast part of their dresses
