There were actually a couple of dresses that looked good on her. Here is what they had in common:
1. They fit.
2. The cut gave her a high waste, but the waste marker was small and subtle (not the boob belt)
3. The skirt wasn’t fitted, but it wasn’t full either, kind of half way between.
4. They were in color but the colors weren’t overbright, more like a muted jewel tone.
5. They weren’t overly embellished. An interesting collar, brooch etc.
Waste?
Waist.
On some of those photos they’re photoshopping her, there’s no way her body shape could change so drastically from dress to dress. I agree that some of the colors are outstanding on her, many are not. She dresses like a 20-something-year-old most of the time.
