Silver blouse - Plastic Island

I think this is truly my favourite top I have ever had. Really unique fabric, like silk, but more luminous. Buttons at one side on waist band. Doesn't need ironing. It is too small for me and have been holding onto it for years as I love it and difficult to part with it. Tag says L but I am posting as a S/M as that is really what it is. Happy to provide measurements. Perfect condition.
