When a lady wears a sari and bindi, there is no confusion about her identity. Clearly, she is a Hindu and she is an Indian. Once you stop wearing sari or stop performing classical dance of India we do not know who you are anymore. You can be anyone or no one. Your identity in that case is not just questionable, it is lost. I am not against wearing this style or that style of dress. I am just saying that traditional dress reveals and preserves the identity of a person.
