Okay so I'm at a loss. I am attending an Indian wedding in August and I have not a clue what is appropriate to wear. I am friends with the groom, and he told me that although I was welcome to wear whatever I want, I would be the only one that wasn't in Indian attire. I thought it would be a once in a lifetime opportunity to wear that gorgeous clothing, anyway. I know I can wear a saree, but can I wear other types of Indian clothing to a wedding? Someone mentioned that a lot of people wear the dresses with leggings underneath (again, not even quite sure what this is, although looks more comfortable when I google it). I don't want to look inappropriate or out of place.
I am going to a indian clothing shop this weekend but wanted a little input beforehand if any of you had attended Indian weddings, or had/are having one. Thanks!
