Not to body shame Stephanie she definitely has a tummy now so why is she trying to belt her dresses? Just wear flow-y tunics and sack dresses with nice details and pretty jewels. Camilla has a tum tum too but knows how to pick clothes that still flatter her. I do love the makeup though it's been very good but with the higher style cosmetics it makes her depression stronger in contrast when the camera catches her staring off in the distance or being sad.
Because she's 35 and not over 70 like Camilla. It's hard for woman, especially one in the public eye, to adapt to not being model type. Steph clearly has not much idea about her body or is self conscious in any way about herself.
A lot of women think that wearing belts or buying a size smaller, will make them look thinner, though it's in fact the opposite.
