What standard is that? The standard of a leading Bollywood star's costume, designed by a highly paid stylist, assembled by a platoon of seamstresses, financed by a major media production company? It's cosplay, yah? Put together on the cheap, in the model's spare time, with enthusiasm, for love and not money. For fun. Remember when you had fun that time? Like that.
To more directly answer your question, "Bollywood" is clearly being used as a synonym of "Indian style", to evoke a feeling. Just as "Paris" or "Hollywood" might be used to denote the style of something that's never been within a thousand miles of either of those places.
