An example of how words evolve over time is your familiar attire, 'Pishvaaz,'  پشواز which is now making waves in the world of fashion. If we trace the history of this word, we get a glimpse of the changing forms of language and culture. Pishvaaz is a flared, long garment commonly worn in Kathak dance and, by women during the Mughal era. These days, fashion designers are creating new outfits based on this very style. Over time, 'Pishvaaz' also came to be called 'Peshwas,' and nowadays, this type of outfit is also referred to as 'Anarkali.

The first recorded reference to this garment can be found in  آئینِ اکبری the Aain-e-Akbari, a noted record of the life and reign of Emperor Akbar
The word 'Pishvaaz' is an altered form of the Persian word 'Pesh Baaz.' 'Pesh' means ahead or in front, and 'Baaz' means open. The 'Qabaa-e-Pesh Baaz'  قبائے  پیش باز was a loose garment reaching down to the ankles, open at the front, commonly worn by dervishes, a dervishes are part of the Sufi ( Muslim mystic ) fraternity who renounces the material world  and depends on alms for sustenance  a member.

 In miniature paintings from the Mughal era, women are often depicted wearing the Pishvaaz. And how could it not find mention in Urdu poetry?

That veil of your badla—oh, like a flash of lightning in sight,
Let this dark cloud compete with the flare of a Pishvaaz
