I think the groom attire shouldn't stand out too much from your bride's outfit. I say this so that you understand that women love to be the center of attention. If she's wearing a burgundy sari, then you should find a groom's attire that isn't too flashy. You shouldn't wear a gold-colored sherwani because it doesn't look good with burgundy and cherry colors. You can look for a dark metallic sherwani or a silver sherwani in a darker shade. I'd also look at a black or very dark burgundy, almost black sherwani. Then your bride and her family will be happy with your outfit. Congratulations on your wedding.
