Kerala traditional set mundu or set saree is not a "pure white" one. Its kind of milky white or offwhite in colour. And earlier in Kerala people used to dress in very simple cotton clothes. So without dying the cottons , these offwhite colour came into existence. and if you see Christian weddings they also wear pure white sarees/gowns for their wedding . So since its a offwhite and gold comibation u can wear it with pearls or gold jewellery . It will gives u a very rich luk. Try it out.
