cowboyish swagger, romeo-style red scarf

The only time Bollywood cast Rajnikant in an important role was in Anil Sharma's 'Farishtey', J. Om Prakash's 'Bhagwan Dada' and 'Wafadar', which were forgotten soon after. But except for his crisp Tamil accent, a Romeo-style red scarf, a cowboyish swagger, there was little to write home about his Bollywood career.

I know meaning of `scarf' and `swagger' in general. But I can't understand that in this context.

Could you explain the bold parts please?
