Why did Lando take Han's clothes?

I always thought it was strange that at the end of The Empire Strikes Back, Lando changes into what looks like Captain Solo's clothes. Why is this? There could be so many reasons. The first possible reason was that these were Lando's clothes to begin with. When Lando lost the Falcon to Han in a bet gone bad, the clothes came with the ship, so Han took over possession of both the ship and clothes. That seems strange though, but could lead to the second possibility; the clothes are an actual uniform for the Millenium Falcon. That would beg the question, why did Chewbacca not wear the official uniform of the ship? Perhaps being a harry Wookie would answer not wearing the pants or shirt, but at least the vest? Or, just the captain of the ship wears the uniform? More questions are raised when you look at this package...


'Lando Calrissian in Smuggler Outfit!' This means that the uniform is a smuggling outfit! Which is very strange, because one would think this profession to be very secretive. I would hate to be caught smuggling spice at Walmart just because I was wearing the flagged smuggler's outfit.

Oh well, I'm afraid I still can't answer this most strange situation. Can you?
