A kurti set is built around a long tunic worn with pants and usually a dupatta, and those pieces only need to co-ordinate — a plain bottom under a printed kurti still counts. A co-ord set is stricter: the pieces share the same fabric and the same print or embroidery, and the top is as often a shirt or a short kurta as a long one.

Cotton and linen. Both breathe and let sweat evaporate instead of holding it against the skin, so they do not cling in humidity. Linen runs slightly cooler and dries faster but wrinkles more visibly; cotton creases too, which is simply what the fibre does. Silk and organza are warmer and better kept for evening functions.

Yes, for the daytime and lighter events — a mehndi morning, a puja, a haldi, a family lunch. Choose an embroidered set in silk or organza rather than a printed cotton one. For the ceremony itself or a reception, a lehenga choli or a saree carries the weight the occasion expects.
