Kate Middleton really loves shopping her closet (and frankly, who wouldn't?).

The Duchess of Cambridge attended an event at the Natural History Museum on Wednesday with hubby Prince William wearing a gorgeous black lace Temperley gown that she had previously worn twice in 2012.

Prince George's mum first sported the gown when she attended the "War Horse" premiere in London and again at the 600th anniversary of St Andrews University last November. (Lucky girl, she can still fit in it even after giving birth back in July!)

This time, the Princess wore her iconic brunette locks straight and glossy but she sported the same black belt and diamond bracelet that she wore last year.

Both the Duke and Duchess were at the museum to attend David Attenborough's film premiere (they even wore matching 3D glasses!) and William looked every inch the prince in a classic tuxedo.

This is the second time in two weeks that the 31-year-old attended a red carpet event in a Temperley ensemble. On Nov. 28, Kate wore a similar, albeit more casual, frock to the SportsAid Charity Dinner.

The couple also paid their respects to the late Nelson Mandela earlier in the day, with Kate wearing a chic polka-dot blouse and skirt ensemble.

Do you think the gown looks just as good the second time around?
