January Jones's Tough-Girl Maternity Style

Before welcoming son Xander Dane on Sept. 13, January Jones uses an Alexander Wang drawstring bucket bag to keep her belly chicly hidden as she visits a friend in L.A. on Sept. 3. A straw fedora and dark shades complete her incognito look.

Is she or isn't she? Despite being very pregnant, the mom-to-be's growing belly is camouflaged by a roomy striped strapless maxi dress and oversize blue cardigan during an Aug. 27 trip to Trader Joe's in Los Feliz, Calif.

For an Aug. 19 doctor's visit in Santa Monica, Calif., Jones keeps it casual in an off-the-shoulder white lace top, Paige Premium Denim jeans, wedge sandals and a bright green bag.

The expectant actress plays up her neutral ensemble with pops of lime green and orange for an Aug. 10 shopping trip at L.A.'s Century City Mall.

For a July 22 lunch date with friends in Los Feliz, Jones expertly pulls of the nautical trend – and shows off her gams! – in a blue-and-white striped mini, red sunglasses and chain-link bag.

A day before the Fourth of July, Jones – who is expecting her first child in the fall – takes a style cue from Mad Men's Don Draper, pairing a retro fedora with a striped white maxi and loose Vkoo cardigan on the beach in Malibu, Calif.

For her June 25 ocean-side baby shower, the mom-to-be picks a blue Zara floral dress and shields her eyes with pink-framed sunglasses.

While running errands in Beverly Hills on June 14, the X-Men: First Class actress flaunts her assets, picking a ruffled, printed mini that shows off her slim legs and topping it with an Express cardigan and strappy metallic flats.

On June 11, Jones belts a printed Tucker maxi dress and adds a cozy cardigan and comfortable lace-up work books for an edgier look.

During a day out in West Hollywood on June 3, the expectant star gives that same style a twist, opting for a bright minidress but keeping the same comfy kicks and cover-up.

While promoting X-Men: First Class in N.Y.C. on May 26, the actress mixes easygoing with fashion-forward, choosing a navy-and-black crochet-top dress and nude Rosegold sandals.

At the May 25 N.Y.C. X-Men premiere, Jones glows in an elaborately draped purple-and-black Preen dress and sexy, strappy black heels.

She's already multitasking! The mom-to-be texts and strolls in a long-sleeve tee over a Hermès belted floral miniskirt and lace-up combat boots while out in Santa Monica, Calif., on May 6.

Shortly after announcing her pregnancy, a great-feeling Jones steps out in a blousy top, black leggings and her trusty Marni bag.

The stylish mom-to-be adds a sweet touch – white scrunch socks! – to her lace-up boots, baby-doll dress and brightly printed bag while grabbing lunch in L.A. on April 26.

Talk about California cool! The actress pulls together her breezy outfit (oversize sweater and floor-length floral maxi skirt) with an Express fedora and Givenchy bag while out in Beverly Hills on April 14.
