It would mean so much to the bride if you can dress to impress and consider Indian attire. Men can wear dress pants, dress shoes, with a button down shirt or for Indian attire a Sherwani. Women can wear a lehenga, saree, kurta suit, anarkali, or Indian inspired outfits.
Please avoid all pastels, white and red. White and red are the colors the bride will be wearing. The best colors are jewel tones no matter how bright.
