The wedding took place on Monday at a resort in a restored 13th century Tuscan village in Italy, and Mr Mukherjee ensured there was a timeless aura about the clothes and accessories for the bride and groom.
"We designed the clothes for both bride and groom for all the functions. From engagement to mehendi and sangeet, for the wedding and post-wedding dinner, and heritage jewellery from recently launched Sabyasachi label," he said.
"It was wonderful to work with the couple. From the House of Sabyasachi, we wish Anushka and Virat a very happy married life," Mr Mukherjee said.
The designer ensured Anushka sported a different look at every function. For her mehendi ceremony, he says she wanted a look full of bright colours.
Artists from The Sabyasachi Art Foundation rendered a beautiful sixties pop print and it was silk screen printed, hand woven Indian silk, Mukherjee said in an Instagram post.
Anushka went for a velvet sari for the engagement in the label's "signature Gulkand Burgundy".
Her look was complemented with kohl-rimmed eyes, red roses and the label's iconic micro-dot bindi.
For the D-day, Anushka wore a pale pink lehenga with Renaissance embroidery in vintage English colours embellished with silver-gold metal thread, pearls and beads. The bridal jewellery, handcrafted with syndicate uncut diamonds, pale pink spinel and baroque Japanese cultured pearls, was by the Sabyasachi Heritage Jewellery collection.
The groom looked smart in an ivory raw silk sherwani hand-embroidered in a vintage Benarasi pattern, with an old rose silk kota safa.
