Vastra is a Sanskrit noun meaning cloth, fabric, or garment, and it survives in modern Hindi and several other Indian languages with the same core meaning. Because the word is generic rather than coined, it appears in the names of many unrelated clothing businesses across India and in diaspora communities abroad. Sharing the name does not imply any connection between those businesses.
On Long Island, the name fit a specific retail niche: Indian ethnic wear for occasions such as weddings, festivals, and religious ceremonies. Hicksville's South Broadway corridor has long been a destination for South Asian shopping in Nassau County, and boutiques there typically combine ready-made garments, custom tailoring, and rentals. The documented profiles of Vastra Boutique — rental and custom women's clothing, lehengas, sarees, and jewelry — match that pattern exactly.
