She is a very attractive woman, has a great smile and expressive eyes. However, that being said, she needs to watch overdoing eye makeup, so much shine on her face and hair falling over an eye, or forehead.
Regarding clothing, any hat that looks like an upside down bucket should be avoided, as well as high necked furs, or collars, or boxy cuts on suits, pockets on same, no wide belts. Unfortunately, she does need to watch color choices as well, perhaps something with a diagonal line would give illusion of height.
In the meantime, watch the diet and exercise. It seems she has done some work in this area, as one can see a waist reappearing in some pictures. It might take a while, but she can definitely do it. It's worth it.
In some outfits she looks slimmer than others, and she should stick to those as the pounds melt.
