It's not hard to see why Jennifer Aniston's plunging black dress is getting a lot of attention!

Fans are still drooling over the future Mrs. Justin Theroux's daring, cleavage-baring gown she wore Saturday, Oct. 27 to the LACMA 2012 Art + Film Gala in Los Angeles.

Aniston, 43, risked a nip slip in the floor-length Tom Ford dress while posing with Theroux, 41, who looked handsome in a black Tom Ford tux and bowtie.

The actress accessorized her sexy ensemble with another show-stopper -- her engagement ring! "Her ring is huge," an onlooker at the event told Us Weekly. Jewelry designer Peter Meksian from Michael M told Us the estimated price tag of Aniston's giant bauble is $500,000.
