Two years ago, Nishka Ayyar was struggling, like many of her friends, to find a dress to wear to her first homecoming dance. 

The dresses she saw in Bay Area stores and even online were too pricey for something she didn't think she would wear again, particularly since as a member of the homecoming court she needed something to match the green and yellow colour scheme.
