Shopping/Touring in Delhi (New Delhi)

Hello Friends,

I will be in Delhi for 2 days and with such a short time, I would like to make the best of it. I will be attending a wedding and would need to shop for a few outfits. Nothing too fancy but surely tasteful and appropriate wedding attire.
I would love, love, love your recommendations for ladies in Delhi if you could share your best spots to shop things like Lehengas and Salwars, as well as inexpensive jewelry. Someone already advised to drop by Chandni Chowk as a start.

Looking forward to your tips,
Thank you

Christiane
