Way to rock the maternity coat, Kate.

I can't get enough of Michelle Obama and the Duchess of Wales' clothing.  Their outfits make me want to dress all professional for my job (but my job isn't a business professional type of gig). 

I love pretty much everything they wear, including the coat Kate wore for her last public outing before Prince/Princess #2 is born.

I'm always wondering what she's wearing under there since she never takes of the coat.  Is it a dress or just a slip or maybe just her nickers?
