Crop Top Christmas?

   

With midriff being the new cleavage, questions have risen. How much is too much? And where is it appropriate? 

Tons of celebs have put their upper two abs on display on the red carpet. I wonder if they save money on spray tans by just getting half their tummy tanned..hmm..but can this trend be transitioned to real life events and soirees? Perhaps even the upcoming company holiday party?
