Some of the reasons I feel are:
1) He wants Rumpa, the designer - to be mentally and emotionally occupied with reforms needed in his whacky dressing style, while he is busy pataaoing the doc!😳
2)It is a desperate attempt from his end to not look like a geek , a book-worm...a nerd😛
3) He wants to outshine Rajbeer in the 'looks' department, and grab Amrita Rao's attention , hence tries all possible skills at decorating himself.⭐️
4)To add some splash color in life of his sad, melancholic mommy...who is traumatised by Gulabo's evil advances towards herself 😕
5) He is a nature lover...who loves every girl...every color...every pattern....every design.....so wants to add and have 'everything' in his life...😉
6) Any other..
so what do we all feel are the best reasons.....real motive...behind his ohh so pretty clothes....😛..Reason # 1, 2,3,4,5 or anything else 😳?
