January Jones Attends Comic-Con In A White Jumpsuit, And We're Convinced It's Summer's Must-Have Closet Staple

Apparently, summer 2015 has a definite It item, and celebrities are showing it off all over the world, like January Jones at Comic-Con and Sienna Miller at Wimbledon. That's right, ladies. It's time to move your sundresses, mini skirts, and LWDs out of the way and make room in your closet for the white jumpsuit.

Sienna Miller's white Galvan jumpsuit arguably won Wimbledon this weekend, and across the pond (on the same weekend), January Jones was also making a case for the sleek onesie. The Mad Men actress attended The Last Man on Earth panel at Comic-Con on Saturday in San Diego, California and looked summery in a white, Zimmerman jumpsuit. Though Sienna's jumpsuit gave us chic and modern, January went for a more romantic, feminine approach. With lace panels across her chest and at the hem of the wide-legged pants, and a bow belt cinching her waist, the 37-year-old looked soft and flirty, the girlie-girls way to rock a jumpsuit.

And the two blonde stars used their hair and makeup to compliment their contrasting styles as well. While Jones went for a pale pink lip and loose curls, Miller brought the attitude with bright red lipstick and her blonde bob deeply side parted and styled in undone waves.

It was edgy vs. feminine, and both ladies' flawless styles prove that this silhouette is way more versatile than it might seem.
