Wedding shopping recommendations in Mumbai under 4 days

For context, we are visiting Mumbai to shop for bridal and groom attire. We have 4 days to shop for everything so any advice is welcome. We are looking for areas around Santa Cruz, andheri or thane. Budget range is mid - nothing too fancy but also want to avoid the massive crowds in Dadar. Can you guys recommend stores and itineraries on how we can find the best in the time we have?
