If Logans rich, why is he always wearing the same T-shirts/wearing that puka shell necklace?
We can only speculate that the ultra-rich Logan wants to fit in with his peers, so he doesn’t dress in Armani suits all the time. Or, possibly, this isn’t an incredibly high-budget show, so the costume designers have to reuse outfits. Plus there was a theory that less than observant viewers needed clues to tell Duncan and Logan apart. Choose whichever answer you’d prefer to believe.
