I've had a hunch about this cute relationship for a while now after they filmed a movie together last summer, and I suppose it's wordlessly been confirmed. Kate Bosworth and Justin Long just made their debut (or whatever you want to call it) as a couple, leaving dinner in Santa Monica over the weekend hand in hand. As you may know, Bosworth has been a Who What Wear favorite for many years now, and she remains as stylish and elegant as ever, always serving up perfect outfit ideas.

If it's a date-night outfit you're seeking, I strongly suggest taking note of Bosworth's timeless look for the occasion. She wore a relaxed black minidress with black slingback pumps and a chain-strap bag.

It's as simple as can be and works beautifully for a variety of occasions.
