She was at peace.
Lucy was a bright shining light, and had an incredible dry sense of humor.
Her smile and laughter could light up a room, and draw you closer to her.
She loved to dance, she really shined.
I am so sorry to hear about Lucy.
Rest in peace, beautiful girl, the Italian fashion designer wrote on Instagram.

My beautiful friend Lucy sadly passed today after putting up a strong fight.
I cant even put into words how kind, radiant and caring she was as a human.
Not to mention how insanely beautiful and talented she was.
The model said her AVM was the size of a golf ball and had resulted in her suffering seizures.
