Jump for Joy! We adore the fantastically yellow gown she donned at the Art of Elysium Black Tie Gala this week. The strapless neckline is huge right now and we especially love it on JB.

So why do we always talk about how much we like this lady? Well, her "joy" (you can't teach that!) for fashion exudes through her clothes. She doesn't always choose the easiest things to wear but always manages to look comfortable and confident. That is the key to fashion. The two C's we'll call it! Write that down.

And please note, the shadow of yellow Joy has on – a light pastel sort of color – is the most universally flattering. So if you wanna get sunny this summer, opt for a very slight yellow if you're unsure.
