Perfume Business in India

Hello Fragheads, i need an input of yours about starting a perfume retail business in India, specifically in Delhi NCR. If anyone can help me with what all should i research about before stepping into this be it suppliers, startup cost or choosing the right distributors. I need suggestions on how do i reach out to the customers like should i open an offline store or focus on selling online. If anyone has an idea about should i need to visit Dubai to seek genuine distributors or not?

If anyone could help me or give a brief overview about how to start this, i will be really greatful

PS- I want to sell genuine designer, ME and niche perfumes.
