try or forget? peek a boo bras

I kind of want to try this really bad...

But I'm afraid of it being trashy...
I mean this is just bad:

But this works really well:Maybe the idea is to keep it simple and classy
1) Bras should neutral colored (black, gray, etc)
2) The top should be fairly loose and comfortable
{seems like cutting of the sleeves a t-shirt would work}
3) Keep everything else simple too
{i.e. Rihanna's hair, tight dress, trashy bra color, nooo}

Would you try this?
