Question How Much Does Clothing Cost in India?

I'm planning a trip to India in October, and shopping is at the top of my list. I know Delhi and Mumbai have great shopping spots, but I'm curious about the cost of clothing there. I'm interested in both ethnic wear and western wear, especially branded products. If branded items are cheaper in India, I might wait to buy them there instead of shopping in the UK before my trip. Does anyone have insights on the price range for clothing in India? Also, are there specific months when sales or discounts are more common?
