Consider incorporating technology, like smart fabrics or customizable clothing options, differentiation in a big way. Like the one which came in shark tank? Trums.
I believe Shark Tank India will be dead by season 5 whereas Shark Tank US remarkably is going on for 16 seasons.
Same old clothing and food startups makes it kinda boring.
In US a 16 year old boy came on shark tank to ask for funding the Shark's Got Interested and supported him and In India 16 year old boy also came on Shark tank and got advice like "pehle padhai khatam krlo baad mai aana" . A Huge Mindset Difference !
