While there are some Bollywood-stricken Pakistanis who are obsessed with copying any and all Indian trends, overall tastes are very different and I don’t see that changing anytime soon. Indian clothes are (rightfully) seen as tacky in Pakistan and I really don’t see why that’s “bound” to change.
If anything, I think that as Indian society modernizes, they’re going to adopt a more Western aesthetic with less gaudy embroidery and more muted colors.
