OK, we're a bit pulled back for this shot, but you need to be so in order to take in the whole picture. Obviously, the first thing that catches the eye would be the banana yellow pipecleaner pants that are so tight even Joey Ramone would be uncomfortable in them. And who wears a scarf with a t-shirt? I mean besides, apparently, 80% of Bollywood?
Unfortunately, the video is of poor quality so you can't really make it out, but his shirt says "Super Disco" in sparkly letters.
Now, compare his Dick Tracy primary colored outfit to Sridevi's outfit from the same scene:
Hers is a timeless classic, I think we can all agree.
The lesson to be learned here, however, is simple: if it's warm enough to wear a t-shirt, it's warm enough not to wear a scarf. If it's warm enough for Sridevi to take a bath outside, it's warm enough not to wear a scarf.
