Will Reliance and Shein destroy ZARA, H&M and ZUDIO? | Business case Study

Mukesh Ambani beginning a fashion revolution with the most powerful brand in the world which is SHEIN and I must tell you, ZUDIO ZARA and H&M and in deep trouble!!!
If you Remember when the Indian government banned Chinese apps in 2020 over data privacy there 2 big giants who got kicked out of India, one was TikTok the fastest-growing social media platform and the other was a legendary fashion brand that we all know today as Shein!!! And if you Shein is just another fashion brand look at this, Zara and H&M are the most successful fast fashion brands in the world!!
In 2024, while Zara with 2200 stores generated a revenue of 29.1 billion dollars, H&M with 4300 stood at 22 billion dollars where as Shein alone has generated a revenue of $48 billion USD by 2024. So Shein generates almost the same revenue as H&M and Zara combined that too without a single store in the world!!!!! And now shein is in India to wage a fast fashion war against the most formidable brands like Zara, H&M, zudio and Snitch!!! Its not just Shein the mammoth but Shein the mammoth with the godfather of Indian business who goes by the name Mukesh Dhirubhai Ambani!!!
The question is
How on earth does the world of Fast fashion work?
How did Shein become the godfather of Fast Fashion in the world?
And With Shein in India with Reliance whats going to happen in India???
