Happy days I managed to ID this look. I love the simplicity of this look Margot wore during a photoshoot with Diego.
Margot is wearing a Me And Em High Shine Sheer Dot Pussybow Blouse in Cream, available for £175.
Margot also wore Me And Em Transformer Tailored Trouser with Removable Braces in Black and Satin, priced at £225.
