Alok, one of the largest textile manufacturing companies in India, is a major shareholder in the British retail chain already.
According to the value retailer, the move will provide a strong financial platform for future development and help to fund a multi-million pound refurbishment across the entire portfolio of QS stores.
QS group chief executive Findlay Caldwell said: 'This is fantastic news for our company and all our employees. It will enable us to strengthen our position as the best value-for-money fashion retailer on the high street.
'We are operating in a large and growing market in the UK and the board welcome the expertise and financial commitment of the Alok management team in helping us develop the business.'
Value fashion brand QS has 207 stores across England, Wales and Scotland. Alok group chairman Ashok Jiwrajka said: 'Alok Group has recognised the growth opportunity for QS and is confident that this significant investment will accelerate this growth and enable it to be realised.'
