Nicole Kidman at the Critic’s Choice Awards in Santa Monica december 2016, wearing a vintage brooch on the sleeve of her dress

I found a photo of Nicole Kidman attending the Critic’s Choice Awards in Santa Monica last year. Do you see where she is wearing her vintage brooch? Pretty fancy place! The geometric pattern of the brooch compliments the triangle forms of her dress. I have in my shop a Mauboussin diamond spray clip from the 1950s. I’m looking for the dress that goes well with this form. Maybe an asymmetric dress from the retro period. Anyone?
