Single looks good on Jennifer Garner!

The 43-year-old actress stepped out sans wedding ring on Tuesday to attend and host a Chanel candlelit charity dinner held at the Chanel Robertson boutique in Los Angeles. It marks her first formal red carpet appearance since announcing her split from Ben Affleck in late June.

The event was an intimate affair, with 70 guests all coming together to support and raise money for Baby2Baby, a non-profit that provides low-income children with basic necessities. Other celebrities in attendance included Jenna Dewan-Tatum, Selma Blair, Rachel Bilson, Ellen Pompeo, Rachel Zoe and Molly Sims.

Garner's first post-split public appearance was earlier this month, at the Think It Up education initiative fundraising event hosted by the Entertainment Industry Foundation (EIF) in Santa Monica, California. The Dallas Buyers Club actress dressed much more casual, rocking a simple fitted tee from the organization and black skinny jeans.

Affleck and Garner announced they were divorcing on June 30, just one day after their 10-year wedding anniversary. Rumors swirled that the reason for the split was due to an alleged affair that Affleck had with the couple's former nanny, Christine Ouzounian, but Affleck's reps have vehemently denied that to ET.

While both Garner and Affleck have been seen around Los Angeles over the last couple of weeks without their wedding rings, the two have appeared amicable since calling it quits, keeping a united front for their three kids, Violet, Seraphina and Samuel. They have attended doctor appointments and counseling sessions together in California, and Affleck regularly traveled to Georgia while Garner was filming the movie Miracles From Heaven in the Atlanta-area. The entire family even traveled to Florida to celebrate Affeck's 43rd birthday in mid-August.

Just last week, Affleck and Garner were snapped again together, having a friendly sushi dinner in Malibu, California. Watch the video below to hear more on their night out.
