This exact faux fur coat is sold out (Ann Taylor size petite xxs) but I’ve linked some similars, including from brands that tend to run petite-friendly. The grey coat is a petite size.
The pants are size 25 but 24 also worked on me. I had them altered to get the length cropped and knee slimmed.
The tee is available in the Chateau Marmont online shop. I’m in size medium.
