Duchess Kate Middleton sparkles in tiara and ethereal red gown in new family photo

If you need something to brighten your day a little bit, allow Duchess Kate to help.

In a brand-new royal family photo from the annual reception for members of the Diplomatic Corps at Buckingham Palace, the famous mom of two stole the show in Princess Diana's signature tiara and a red Jenny Packham dress fit for a princess.

See the photo everyone's talking about and all of the Duchess' appearances in a tiara below:

As you can see, Kate wore the same tiara belonging to her late mother-in-law at last year's dinner -- and she's only worn a tiara at all a handful of times before that, including at her wedding to Prince William in April 2011.

And if the dreamy red gown looks familiar to you, it's because Kate has flaunted it before -- at her first state banquet in October 2015.

She seems to really love it, but if she'd be so kind as to let us borrow it for our holiday festivities, we'd be forever grateful.

... if only!

If not, we guess we can settle for this equally breathtaking -- and fairly similar -- Packham gown.
