Liv Tyler - Triumph Essence Lingerie, Autumn/Winter 2017
I don't think those enlarged boobs are fake. She has gained weight and the chest just appreciated accordingly. (Ditto the boo-tay.)
I remember reading that she had to keep her weight under 127 when she was filming the Lord of the Rings movies. That clause was added to her contract because she had gained weight at various times in her life, and may have a genetic predisposition to weight gain (she has a half-sister who is obese).
But she's pretty close to six feet tall so, while that mandatory 126 may have been justified cosmetically, the clause did not really consider her health. It took three years to film those epics, so she was probably starving herself constantly for that entire time, hence the chest looked a lot smaller back then.
