I searched quite a while for this sweater but thankfully I can now share the ID.
Under her warm winter coat, Margot wore the Aritzia Wilfred Free “Naomi” Sweater in the colour Goldfield Yellow. The sweater has an oversized turtleneck and is cropped, which shows a glimpse of her white tee. It’s currently unavailable to buy. Thank you to @sarah1987w for the ID.
I feel like these are a fitting choice of pants to wear while in the midst of filming her role as Harley Quinn. She wore a pair of Lykke Wullf “Jessie” Zip Up Pants that are available on California Drifters in the sizes Small and Medium for $231. The pin stripe pants feature a cropped leg and front zipper.
Now onto Margot’s other items which are ones she has worn before. She wore a pair of Vince Camuto Jendeya Convertible Studded Loafers in Black. These are currently on sale for £61.55!
It’s been a hot minute since she wore this coat, but she brought it out once again. She wore her Burberry Felted Wool Double-Breasted Coat which happens to be a favourite of hers and easily confused with her Wardrobe NYC coat!
Lastly, around her chest she carried her Lei Loop Crossbody Phonecase Necklace in Green Camuflage which is available for $24.95 for various phone models including iPhone and Samsung.
