Best Costume Design
Will Win - Phantom Thread
Could Win - Beauty and the Beast or The Shape of Water
Should Win - Beauty and the Beast
Commentary - The CDG passed over Phantom Thread for The Shape of Water, but I think that BAFTA and Critics Choice, a broader group of voters means that previous winner Mark Bridges will win again for his fashion designer threads. I still cannot imagine how Beauty and the Beast doesn't win here, but its up against two Best Picture nominees so I guess it is out. But seriously, don't be surprised if it upsets.
Best Makeup and Hairstyling
Will Win - Darkest Hour
Could Win - Victoria and Abdul or Wonder
Should Win - Darkest Hour
Commentary - Biopics do really well here, and the transformation of Gary Oldman to Winston Churchill is just the kind of work that Oscar voters love in this category. I would honestly be shocked it Darkest Hour doesn't win the gold.
