Jewellery is planned function by function rather than one heavy set worn everywhere, but what goes where depends on your pieces, your family's heirlooms and how long you'll be wearing them. Many brides keep the weightiest set - polki, kundan or temple, depending on tradition - for the ceremony and something lighter for haldi and mehendi; we'll suggest a sequence once we've seen what you own and what you're buying.
Footwear needs to be decided before the final fitting, not after, since heel height changes blouse fall, drape length and how a heavy lehenga skirt sits at the ankle - bring the actual pair to your fitting. Accessories such as potli bags, maang tikka, nose ring and waist belt should be chosen to work with the neckline and drape rather than added at the last minute; a waist belt, for example, needs a lehenga waistband cut to sit correctly under it.
