Jennifer Garner has never looked better! 

The mother of three has been serving up some serious style in New York City -- and showing off her fit bod while doing it.

Garner stunned in a one-shoulder sweater and fitted black pants while out and about in the Big Apple on Wednesday. The 45-year-old actress looked fresh-faced as she struck a pose (and put her toned arms on display) after exiting her car. Garner accessorized her ensemble with minimal jewelry and chic black pumps. She let her long, brown locks flow over her shoulders, and finished the look with a perfect pink pout.

Then on Thursday, Garner radiated while stepping out of her Tribeca hotel, rocking a black satin dress and matching heels. The Alias star was perfectly poised as she headed to Vanity Fair's Founders Fair, where she chatted about her company, Once Upon a Farm, which offers a line of cold-pressed organic baby food and applesauce. 

"Thank you, @kristasmith, @radhikajones and @VanityFair, for including @onceuponafarm—and me!—in today’s #FoundersFair. I love that you gather entrepreneurs to share stories and I ❤️❤️❤️ that they all happen to be women!" she wrote on Instagram. "Krista, you make it easy. You’re the best, thank you. X."

Garner is all about girl power these days, and a source recently told ET that she's in no rush to return to the dating world.

"She wants to be very careful and very selective when she does find the time to date -- because of the kids,” the source said of Garner and her three children with ex-husband Ben Affleck: Violet, 12, Seraphina, 9, and Samuel, 6. “She hasn't made dating a priority.”

“Jen wants to make sure that, when she finally does decide she is ready for romance, that her next man is in it for the long run,” the source explained, adding that the actress is focused on her work and family. "She is back. She has thrown herself into her work and her success. She is killing it and those [closest to her] couldn't be more proud.”
