How do you wear this top?

Hey Guys,

So you know the t-shirts that say:

This is what spoiled looks like

or

This is what gorgeous looks like

Or something on the lines of that, well how do you wear them without being like obnoxious and full of yourself?

Like a top similar to this:

I'm just confused because I have two t-shirts like this from my sister that were hers and it's a shame if I never wore them so I was just wondering how I could wear them without being like full of myself?

Thank you so much!
