Kate Mara and sister Rooney Mara were quite a pair at the SAG Awards on Saturday. Noticed not solely for their acting skills, the sisters both wore cleavage-baring Valentino gowns that caught the eyes and cameras of many in attendance.

Lest you think Rooney and Kate Mara wore matching gowns, that is definitely not the case. Choosing the same designer likely proves the depth of their sisterhood.

Kate Mara wore a beige halter with revealing side cutouts, while Rooney chose a v-neck pleated gown with matching cape. It was by far the less attractive of the two gowns–lending to the appearance that Rooney Mara was about to take off and fly. When she omitted the cape, however, there was some sex appeal.

“I don’t know if this is sexy by most people’s standards,” Rooney said, “but for me it’s more revealing than normal.”

Yes, Rooney and Kate Mara both stunned in their cleavage-baring gowns, but for completely different reasons. While Kate Mara’s look was sexy and inviting, Rooney’s made those nearby do a double-take, but for all the wrong reasons.

An aside: While at the SAG Awards, Rooney and Kate Mara let insiders know that most people have long been pronouncing their last name incorrectly. While most say “Mah-ra,” it is in fact “May-ra” instead.

Neith Rooney nor Kate Mara were nominated for a SAG Award, but Rooney received an Academy Award nomination for Best Supporting Actress for her role in Carol.
