How much margin is there actually in saree reselling?

I’m considering starting a saree reselling business through Instagram and I’m trying to understand the economics before getting into it. For people who are already doing this, how much margin do you typically make per saree after accounting for the wholesale/supplier cost, shipping, packaging, payment gateway charges, discounts, returns/RTOs, and other expenses? I’m particularly interested in the actual net profit margin, rather than the difference between the buying and selling price. For example, if a saree is sold for ₹2,000, how much would you realistically expect to keep as profit? Also, does the margin differ significantly depending on the saree category (cotton, linen, silk, handloom, etc.)? Any insights from people actually running Instagram saree businesses would be really helpful.
