Poppy Delevingne At The Races, Melbourne.

Poppy Delevingne at this years Derby Day as a special guest in the Lavazza marquee.

She is wearing custom J'Aton Couture, Dolce and Gabanna golden crown and matching gold sparkly heels.

If you think you have seen this dress before, you're so right, it is a re-worked design 

of the dress Bec Judd wore to last years Polo.

The lace cut-out detail of the dress was a stand out; and while Derby Day is a traditional "black and white" themed event, 

with her golden jewels, Poppy looked like the Queen of the Lavazza marquee.
