Saraswati Cloth Emporium is the shop you should head to if you're looking to buy saris for a special occasion. Although, they have simpler saris and suits, we recommend you go here for their pretty net saris with zari embroidery on them. Personally, we loved this super elegant sari they had in a grey hue, made of net and embellished with gold pearls (major Tarun Tahiliani vibes) (priced at INR 2,000).
Most of their products are priced at INR 800 and above.
