My final Crimes of Passion outfit post is in the works, but in the meantime, if you liked the look of the interiors, here's something you can actually buy!
I was really struck by some of the interiors in episode three, 'No More Murders', especially Elisabet Matson's curtains. Then, when I was flicking through Sanderson's website to see if they'd revived any more midcentury archive designs (they haven't, boo!) I realised that the curtains are from Sanderson. It's part of their '1950s Fabrics' range, it's called 'Seaweed', and was designed in 1954. There are four colourways, and I liked the teal/orange colourway used in the programme best. Sanderson fabrics aren't cheap, and the prints are large-scale so probably won't suit very small rooms (I couldn't use them in my little Victorian terrace), but if I had the space and the money I'd definitely buy them.
