Nearby at Tu Luc Bookstore, manager Eric Duong estimated that 70% of the Vietnamese-language books on the shelves are imported from Vietnam.

Sainsbury's sells clothes under the brand name Tu and a spokesperson said: "Customer feedback is really important to us and we share Georgia's passion for offering a choice in style of school uniform."

Tu said its school clothes were categorised by age and not labelled by gender.
