Is observing veil necessary these days?

To observe veil is necessary for women.The following information will hopefully make it easy to understand the rulings about Islamic veil.
 
Verse:
“ Allah And remain in your houses and do not stay unveiled like the unveiling of the former days of ignorance.”
[Kanz-ul-Iman (Translation of Quran)] (Part 22, Surah Al-A3zab, verse 33)
 
Commenting on this verse, Allamah Maulana Sayyid Muhammad Na’imuddin Muradabadi has stated: The former days of ignorance refer to the pre- Islamic era when women would strut proudly, display their beauty and attractive features (i.e. jewellery, attractive clothes, raised parts of the chest etc.) for strange men to see. They wore garments that only partially concealed their bodies.

Unfortunately! Even in the present era, we see unveiling similar to that of the former era of ignorance. Undoubtedly, observing veil is as important today as it was then.
