Party wear needs to look exotic. Embroidery is the best way to make a fabric or the garment look so. Georgette saris, silk dresses, salwar suits or evening gowns, all look graceful with embroidery. Above all Lehenga and cholis are the best option. Embroidered on borders of the lehengas or covered all over with metallic, shaded or other decorative threads, embellished with zari, beads, shells and sequins even the simplest of apparel seems exotic. Embroidery adorns all party wear alike giving each piece a unique appeal. The inviter will suggest you the right choice what to wear, what would be a good choice to wear. From formality perspective you have the basic options as wedding wear: Lehnga Choli, Saree, or Salwar Kameez. For informal occasions you might try a trendy Parallel Indo-West Fusion suit or a nice salwar kameez. Formal ceremonies often require a lehnga choli or saree however; a nice formal salwar kameez in satin is a nice alternative. Every religion has its own customs and traditions. Even some has specific dress code for formal function. In some cases, Lehngas Cholis are acceptable wear for Muslim events but again this may vary from family to family so please ask the family. Salwar Kameez is usually a first choice for most Muslim religious events also for Hindus. Salwar Kameez, Saree, and Lehnga Choli are almost always safe for any Hindu religious event but as with any culture, traditions vary from family to family.
