Where are all the men getting their wedding guest attire from?

31M, coming back to india to attend my first Indian wedding in India as a grown up. I left India pretty young and have only made brief trips back home to visit grandparents and some extended family. Where are all the men shopping for wedding guest attire? I’m landing in Mumbai, spending a couple of days there before flying to Indore for my childhood friend’s wedding. Are there any stores you’d recommend? Is Manyavar still considered “good” (I remember it was kinda famous thanks to Virat Kohli and that commercial). If there are any other “local” stores that sell good stuff, I’d be interested in knowing where those are as well. TIA! Edit: thank you all for the suggestions. Excited to visit your beautiful city (and try the food that I’ve heard so much about)!
