I've seen clips of her in Big Boss without makeup or jewelry and she actually looks pretty good without it. I think she should try a simple look, and Raman also asked about that and she said she appreciated that.
I think this show is also a chance for people to know Rakhi without the glamour and makeup, because everyone just judges her on that basis. I don't think she has ever had proper makeup artist or designer makeup, because her makeup always looks caked on and you can't see her real skin. Her outfits are also always a bit too gaudy. She should try dressing like she did on Karan Johar's show, when she was wearing Manish Malhotra. This way people will also get to know her better beyond her makeup and glamour, including the bachelors on the show.
