As they said themselves, “The Laura Ashley brand is loved around the world for its quintessentially English heritage and romantic floral designs" - so they start making their "quintessentially English" dresses in China. Laura Ashley really did take the biscuit!
Even though they'd make you look like a bit-part extra from Little House on the Prairie, the Laura Ashley dresses with value are the 70's ones made in Wales and labelled as such.
Its not easy to pin these things down, especially with non-vintage, but Laura Ashley tentatively started outsourcing to China in the mid-80's (clearly too early for this particular dress) but didn't shift everything out there until 2019 when China looked like their last viable market when their financial outlook was rather smelly and brown. If I had to, I'd date it nearer the latter.
