Ebury Mews is a very strange polish. Let's start with the easy part, the colour, it's a pale pinkish lilac. It's got a strong white base, that's almost chalky. But it's also pearlescent, with a pale lilac/pink pearlised finish. Very unusual in my collection.
Swatches are shown with 2 coats. Application was slightly streaky probably because of the white base
This one is another vintage polish but it crops up frequently on ebay for peanutes. And there's a few Ebury polishes, as well as Ebury Mews there's also Ebury Place and Ebury Bridge that I know of...
