You're right, Rajbir. There is nothing wrong with saying costumes. By definition and translation, costumes are what they are.Rajbir said:theres nothing wrong with saying costumes, but if you wana be cultured, they should be called vaardiyan.
you dont call bhangra salsa, you dont call vaardiyan costumes.
However, your analogy is hilarious, though. You don't call bhangra salsa because they are two different styles of dances originating from two different regions from two different time periods. The only thing in common between the two is that they are dance forms and that Joseph Campanella is great at both.
