Jennifer Aniston vs. Angelina Jolie vs... Jennifer Lopez?

Aniston's appearance at Sunday's Oscars gave people major flashbacks to Jolie's now infamous dress from the 2012 Academy Awards, and it's easy to see why: both women rocked sexy, notice-me LBDs from Versace and each totally slayed the leg slit game. (And, you know, there's the whole Brad Pitt thing that constantly gets these two compared to one another.)

The thing is, the two gowns didn't really look that much alike. In fact, if you truly must compare the Friends alum to another famous face, make it J. Lo. See, the "Ain't Your Mama" singer actually has worn the exact same dress before.

Lopez donned a slightly lower-cut version of the glitzy gown for a surprise appearance during ex-husband Marc Anthony's concert at Radio City Music Hall in New York City last August.

The Jolie effect clearly has a lot of, well, leg to it. Five years after her iconic red carpet turn, the thigh-high slit was the biggest trend at Sunday's Vanity Fair Oscar party.

Along with Aniston, more than a dozen starlets rocked the look in widely varied versions. Among those lovely ladies was Janelle Monae, who looked fierce one of our favorite looks of the night, a pretty punk confection that featured a long-sleeved mesh bodice, voluptuous skirt and oversized studded belt.

Mariah Carey nearly spilled out of her patterned Philipp Plein frock.

Rosie Huntington-Whiteley's baby bump made its first major red carpet appearance when the Mad Max: Fury Road star stepped out alongside fiancé Jason Staham in a slinky silver Aterlier Versace gown.

Alessandra Ambrosio put a modern spin on Old Hollywood in a fiery red draped frock, while her fellow Victoria's Secret Angel, Adriana Lima, stunned in gold sequins.

Alicia Vikander's royal-hued lace dress looked almost demure compared to some of the others, and we can't get enough of this gorgeous turquoise sequined gown on Freida Pinto that totally screamed #MermaidGoals.

And Gabrielle Union definitely wins for the edgiest look of the night, which was basically just a few strips of fabric. Listen, when you look this good, you show off that hard-earned bod!
