Khushi needs a new hairstyle. This two booby pins on the side with just one bang on her forehead does not look good on her. She has a decent size forehead she should have some fringe or something other than this little girl bobby pin hairstyle. She is still wearing the same old salwar kameez. She is a bahu now she needs to act responsible. ASR gave her a saree (hint hint) she needs to start wearing sarees. Payal hair looks modern and her saree sense and all is great. Khushi's outfit needs little maturity. She would look amazing in a saree.
P.S. This is just my opinion I am not bashing Khushi as a character at all. So, please dont take in the wrong sense and have conflicts.
