The black body-con dress, which currently retails at £15, sold out quickly after model Lottie Moss was seen wearing the outfit in London.

The dress includes ear straps at the top of its roll-neck, meaning the fabric can be pulled up and secured over the nose and mouth.
A spokeswoman for PLT told the PA news agency: “This has now been restocked so is still available in some sizes.”
The dress was originally available in UK sizes 4-16, however the range is now limited due to demand.
