Perhaps consider (white?) flower garland with pearl or crystal bead accents? According to http://en.wikipedia.org/wiki/Garland - 'In India...flower garlands have an important and traditional role in every festival...Some of those flowers [used] are as follows: jasmine, champaka, lotus, lillies, ashoka, nerium/oleander, chrysanthemum, roses, hibiscus, pinwheel flowers, manoranjitam etc.'
Arti and Amar are both Gujarati, The very first wedding I photographed in India was a Gujarati wedding in 2007 in Ahmedabad. I had not been back since so I was really looking forward to their wedding in Surat.
