This is even more so for someone whose acting skills are not extraordinary. It does not mean that the person is not a good actor but certain persons are like that. A case in the point is Shakti Kapoor, Ranjit, Lalita Pawar, Bindu and a host of others.
Now if we talk of contemporary actors, actors like Gulshan Grover, Prakash Raj, Ashutosh Rana, Sunny Leone, et al. are the ones fitting the bill. This is even more true for glamourous actors. It really becomes difficult for a fan to contemplate an actor otherwise.
Now the reason for our talking about Malaika wearing too many clothes is also a simile to the reasons explained above. Malaika Arora launched the new collection of Satya Paul. And obviously, she wore a Satya Paul saree for this event; and she seldom wears sarees. She's more known for her skimpy dresses. Even in her appearance as an item girl in so many movies, she is known for her jaw-dropping clothes.
