As this is very exciting, we've taken a look through M&S's new-in collection to get a feel of what *might* be included in Meghan's edit. Granted, this *will* change, as the collection will no doubt be an Autumn Winter edit, but the themes will likely be similar. Scroll down to see what we're predicting.
A super smart suit
Meghan knows the value of a smart suit and we all know that an important meeting in the office requires one. Play it safe in this black blazer and wide-leg trousers and add a jazzy accessory - a bright coloured scarf perhaps.
Can't deal with heels? Join the club. These ballet flats are game changers for the office as they look stylish, but they're also super comfortable thanks to the Insolia Flex which recuses the pressure on the soles of your feet.
Is your air conditioning on full blast in the office? You might need some cashmere in your life but that can get a little expensive. Thankfully, M&S has a £15 jumper made from Cashmilon fabric - it's designed to stay cosy and comfortable wash after wash.
Oh how we hope Meghan adds in a dupe of something she has already worn. This knitted dress from M&S is very similar to the frock Meghan wore for the final day of October's royal tour in New Zealand (at a fraction of the price, of course).
Well, Meghan is in the royal family. She might well add a poppy brooch within her collection. All profits (£3.75) from its sale will be paid to The Royal British Legion Trading Limited, which gives its taxable profits to The Royal British Legion and Poppyscotland.
