Sanam's costumes are atrocious to say the least. There is no need to use such tacky color combos , cuts, fittings and untamed hairstyle to show that a character is village belle with financial responsibilities on her shoulders.
They can make her wear simple clothes with bright colors not necessary to incorporate full range rainbow colors in each and every dress. You are so right, tight plait and long unruly hair in front don't come across natural for a village belle, if she takes time to make tight plait, why would she leave such long hair in the front specially when she is in cooking business, where she spends significant amount of time in hot temps in kitchen.
Surbhi has a large forehead and hairstylist want to cover it but couldn't go by old style as it looks like that of Zoya and they took this option, which is a disaster. I would have preferred her having a low combed hair on her forehead but all tied back in to tight plait, that would have resolved Surbhi's forehead semantics and at the same time it would have fit the village belle style and looked appropriate for cooking environment.
I too feel Rehan is grey behind that cute face.
