Short answer
In Ahmedabad, Sindhi Market, Kubereshwar Market (Kalupur), Safal 2, and Raipur Chakla are best for cotton nighties; in Mumbai, Chakla Market (Masjid Bunder), Ulhasnagar, Null Bazaar, and Chembur Camp are the top wholesale hubs.
Cotton nightgowns (maxis), printed kaftans, and 2-piece cotton loungewear sets are high-margin, 365-day staples. Ahmedabad's Kalupur / Revdi Bazaar and Safal 2 specialize in pure 100% Gujarati dyed/printed cotton nighties, while Mumbai's Chakla Market and Null Bazaar / Dongri excel in Alpine, crush-cotton, and embroidered kaftan nightwear.
