Her first trimester saw a seemingly endless supply of leather trousers (or perhaps it was just the one pair - we hope not, given the LA weather and sweatyness of a cow-skin trew).
Then there was the Royal Wedding Bin Bag, and, just last week what we thought was the pièce de résistance: the wet-look dress. But no, Posh has surprised us all again, stepping out in an over-sized knotted shirt smock.
Last seen on Britney Spears in the 1999 Baby One More Time video, the knotted shirt is obviously making something of a fashion comeback, and if you're fit to pop, the way to wear it is baggy, knee length, and with an over sized waist tie.
We're sorry Posh, but for a fashionista, you are NOT wearing this pregnancy well. This frock-horror is most certainly more NOT than KNOT.
What do you think? Has Posh lost the fashion plot with baby number four?
