I'm sorry to say, but Stephanie definitely has bad taste on dressing. When she was 18 years old (young and beautiful), she was dressed very minimal and sportish, so it was nice for this age.
Afterwards she started to dress very "disco", with strong shoulders and voluminous hair, but as she was still young and it was the fashion at this time, it was still acceptable. But since her 28ies she is always badly dressed, very young looking, half nude. She forgets that she is not 25 anymore, she is mother of kids in their 25ies... and this kind of outfits do not even suit to her actual, face, skin and body, and of course not at all to her rank.
Even when (rarely) she tries to be suitable and polished, she quite always fails. I do not understand how difficult could be for a woman with her financial power to have a haidresser, twice per week and to have a normal hairdo.... She looks always like if she jumped from bed, poor and without any help, she put a scrunch on her hair and she ran to work..And most of her dresses look like id she received them "second hand", from another woman, thinner and shorter, so everything to her is too tight and too short.
Sorry, I love Stephanie, she is an attaching and kind person, but since she decides to have official appearances, she should have some help.
