Specially the way she covers her back with the flowing hair is intriguing. Lots of senior actresses (Wont name) show their back even if it doesnt look good. On the other hand, Kratika knows very well that the flowing hair is her recognition and rather flaunts that.
By the way, in few of the recent episodes, she did not cover her left side. And to be honest, it didnt look good and she reverted back to her own style.
Every person has his/her own style. And its not about covering or showing skin. Its about what suits one. May be Kratika knows that very well that flowing hair and the usual way aarti drapes her saree is the best look for her on screen. Very few actresses in the industry have this sense on what looks good on them and their character and find a right balance. You dont want your adarsh bahu ending up showing cleavage every now and then. Sadly some actresses do that without knowing that isnt the look for them.
