Jessica accessorizes a velvet Oscar de la Renta halter gown with a diamond drop statement necklace – and that statement is, "I'm worth $325,000!" – for the Tiffany & Co. Blue Book Ball in N.Y.C.

We'd say she looks bridal in this head-to-toe-white ensemble (an embroidered dress and pointy-toe heels, both Giambattista Valli, plus a matching clutch) and carats upon carats of diamonds at a Tiffany & Co. opening in Paris, but of course, this star wore pink on her wedding day.

Does summer have an official mascot? If not, we'd like to nominate Jessica. Between that oatmeal crop top, her high-waist wide-leg white pants (both Vionnet) and the perfect center-parted blowout, she has all eyes on her at the Tiffany and Co. event in L.A. to celebrate the Atlas collection.

Jessica is one of those lucky girls whose hair looks good in any weather (yes, even that L.A. storm). Case in point: her perfect ombré waves, which she sweeps over one shoulder.

Jessica sticks with one of the big trends of the evening – neutrals with a hint of metallic – by wearing a strapless lace gown, plus tons of Tiffany and Co. ice, which must almost make up for the fact that her best accessory (Justin Timberlake) isn't on her arm.

If your closet had Netflix's recommendation engine, it would say something like, "Because you like plaid button-down shirts, we suggest: plaid button-down dresses." And you'd be smart to listen to your closet because Jessica looks so cool in her Steven Alan design, which avoids feeling home-on-the-range-ish thanks to a tailored blazer.

JUSTIN & JESSICA

After a nearly five-year romance, Justin Timberlake finally asked his ladylove to marry him while the two were on their annual Big Sky Montana vacation. Why there? Apparently Biel, a Colorado native, is crazy about snowboarding and mountains, so the singer-actor popped the question atop a mountain.

If the question were, Who layers her Rails flannel better?, Jess would be the clear winner. But we're more interested in who looks cooler in the plaid button-down.

If we had a body like Jessica's, we'd wear crop tops in December, too. The actress pairs her shrunken shirt with an AllSaints leather jacket, a lacy skirt and print Bionda Castana heels for the Hollywood premiere of The Truth About Emanuel.

Perfectly matching your shoes to your dress: not just for bridesmaids anymore. Mrs. Timberlake teams her strapless tiered Dior Haute Couture creation with pumps that coordinate with the lilac layer and the yellow embellishments at the neckline of her dress for the Guggenheim International Gala in N.Y.C.

If you think underwear shouldn't be seen in public, you'll probably vote for the supermodel, who adds extra lining to her Dolce & Gabbana lace dress. But if you're a fan of exposed bloomers (no judgment), Jess is your girl.

Hot, hot, hot. That's how Jess must feel in this second-skin Christian Dior leather dress, which we want, want, want. The actress also knows the key to jazzing up an all-black midi: colorful shoes and a clutch that makes a statement (both are Christian Dior).

Of those making the trip: Biel's 7th Heaven costar Beverley Mitchell, who four years earlier had asked the actress to serve as a bridesmaid in her own Italian wedding, and Timberlake's frequent collaborators Timbaland, Andy Samberg and Jimmy Fallon. The future Tonight Show host even joined in during Timberlake's toast, cracking jokes with the singer in "a moment that everyone there will remember forever," Timberlake wrote in tribute of his good friend, who was honored in this year's Time 100.
