The dancing style for sure isn't Indian. It looks more like jumping up and down. Generic stuff for Yankee's I assume.
The clothing sort of is, the the pants on the men looks like a trash bag. And the shirts aren't like that.
Indian Men's Clothing = Baggy pants, but the part from the knee-foot isn't very baggy. And then a shirt which is around knee-length. Sandals, no shoes can be worn with it.
The girls clothing seemed like a mix between Indian and Japanese kimono. Though it was more revealing than your average Indian sari.

Most Hindu's/Muslims/Sikhs/Jains/Buddhists/Parsis/and even Jews dress like this.
In area's with large Christian influence they dress pretty much like the average Juan-Lopez-Smith in America.
