Online fashion retailer Asos has dropped out of the FTSE 250 this week, its value slumping from over £5bn to about £320m, signalling a sharp decline for the fast-fashion sector. Once a pandemic darling, Asos now faces a £1bn stock overhang as shoppers return to high streets.
Fellow fast-fashion player Boohoo has also struggled, pivoting away from its core market by renaming its group Debenhams and focusing on middle-aged shoppers online. Analysts say the company has effectively “thrown in the towel” on fast fashion due to collapsing margins.
Both retailers face intense competition from Zara, Shein, Vinted and Next. Shein, in particular, has undercut prices and captured a third of UK women aged 16-24, eating into Asos's core demographic. Its ultra-low price model is a major factor in Asos's sales decline.
The market is tough as consumers prioritise value, with young shoppers particularly squeezed. Chancellor Rachel Reeves is reviewing tax breaks on imports under £135 that have benefited Shein, which could force it to raise prices if closed.
Despite the challenges, Shein's investment in technology and supply chain gives it an edge in rapidly responding to trends, keeping it ahead of older fast-fashion rivals.
