Blake Lively made the rounds last week to promote her latest movie, “The Shallows,” but it is her enviable maternity style that is grabbing headlines.

Lively, who will welcome child No. 2 with hubby Ryan Reynolds later this year, has been showing off some enviable of her flawless fashion choices.

She turned heads on the streets of New York this week after a morning show appearance in a drop-dead gorgeous, neutral number; her growing belly barely noticeable under all the beads and lace.

However, Lively isn’t always that glammed up. The day before, she showed that she can dress down… well, sort of. Showing off a flowy, long dress with a jean jacket, her Instagram caption read: “I mean, it's not a gooooown if there's denim over it. Right?!?”

Even if Lively isn’t exactly caught on-cam going casual, she is the poster child for proving you can look spectacular at all times, even as your belly blooms.

Robin Otto, Zulily’s maternity fashion expert, says, “What makes Blake’s pregnancy style so great is her ability to transition her already fabulous fashion sense into her maternity wardrobe. She does an amazing job of finding styles that are pregnancy appropriate,[which] highlight her cute baby bump but are also figure-flattering in all the right ways.”

And Lively isn’t the only member of the celeb set glowing from more than the summer heat. Kerry Washington, Olivia Wilde and Behati Prinsloo are just a few of the starlets expanding their families.

Pregnant women often struggle to stay cool look hot during the summer months, but Otto insists you don’t need a celeb-style glam squad to pull off a polished preggo look.

“Find breathable, lightweight fabrics that are easy to wear. Dresses and jumpsuits are always an easy item to throw on, while not being too constricting during the warmer months of summer,” says Otto.

For a flawless, paparazzi-perfect yet simple look, Otto recommends dresses paired with lightweight, sleeveless trench coats.

“Another pregnancy summer staple… linen shorts. They are breathable, lose fitting and very on trend.”
