Sevigny of "Big Love” (5)
I believe the answer is:
chloe
'sevigny of big love' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for chloe that I've seen before include "young lady" , "She loved Daphnis" , "Daphnis et -, ballet by Ravel" , "Girl's name" , "Girl" .)
