I agree with this. Although, I think although the clothes aren't the most typically flattering I like that she has the confidence to go for trend based silhouettes.I think she is lucky and that she can carry weight well, very hourglass
I also don't think there is anything wrong with looking larger. The cardigan works well to cinch her in at the waist, and the cream "shacket" is good with the slimmer trousers for proportion.
But there's a big difference between oversized and bad fit which i think the below demonstrates. Typically you'd think cream would make someone look bigger, but the black coat is just straight up bad tailoring. It looks like it's made for someone with wider shoulders to hips so the pockets don't jut out.
