Re: Grandmother's Wedding Saree
its a lovely sari.
hard to believe it is so old (looks untouched!)
you could give it to the kaarigars, they can add kaam to it (if you want to make it fancier).
it really depends on how big of an event you are having, so you can be the judge of whether it is appropriate or not.
(you could wear it on your mehendi or mayoo too btw).
for the blouse, get a solid colour (and you can add kaam to it)
