Hardy Amies silk robe - date?

[prettyold]

I landed a gorgeous Hardy Amies silk robe at Brimfield last week, and I'm having a heck of a time figuring out when it's from. I can hardly find a thing on his womenswear, let alone sleepwear or lingerie, which has me worried!

Here are some pictures, including the label, which doesn't precisely match any of those in the label resource. It looks like it's probably from the 70s or later, but if anyone's got insights on this I'd be very appreciative!

Many thanks.

Hello,

Can you tell us where it's made please?

The waterfall front is a modern (last few years) style and I see nothing here to suggest that it's not modern but a country of origin will help.

Ah yes, it's on the flipside of that tag. It's made in England.
I do have my doubts that it's vintage, though the whole thing about 'by appointment to her majesty the Queen' made me think it could at least be pre-1990, when Amies gave up the Warrant as royal dressmaker.
