Shein's UK sales soared by a third last year creating a huge profit boost for the Chinese fast-fashion giant.
The brand's sales to UK shoppers hit £2bn, pushing its profits up by 57% compared to 2023, its full year accounts for 2024 show.
However, the company said it recognised "higher inflation and increased cost of living may affect customer purchasing habits" going forward.
The brand could also be hit by import taxes after the UK government announced a review of the exemption for packages worth less than £135.
Shein has already put prices up in the US, after President Donald Trump scrapped a tax break on low-value packages.
