This past weekend, I saw a suit that made me think of the song - it was indeed yellow with paler yellow dots.
Why don’t they update this…it is so 1960’s…how about 'yellow polkadot thing bikini"?? 
Purple people?!
Same here.
Since the song causes blood to shoot out of my ears, I’m always too distracted to think about how the bikini looks.
You should see a doctor about that.
Black, with yellow dots. Because it looks hottest that way.
Yellow with large dark-brown dots.
I doubt that the singer cared how you pictured the outfit–you were supposed to picture her without ever seeing the bikini.
As I recall, bikinis used more material back then. Nowadays there isn’t room for more than one polkadot on a proper bikini. 
Not that that’s a bad thing.
