I never heard of her.
But I can explain a bit what hi-so in Switzerland means, if it helps. It is all about pedigree, education, business success and most of all decency and discretion.
Switzerland is a very, very rich country but mentality is extremely conservative in that sense, most important are hard work and decency, due to country’s protestant roots.
This is not Hollywood or Dubai, there is no flashing and bling. No logos, no bragging, if you want to brag, you talk about how much hard work you do. Everyone works, even if your father is president of the country, you will work for salary somewhere. For example, celebrities are considered cheap and tacky and when they come, they often complain that people either ignore or dont recognize them.
Who is considered hi-so: old swiss dinasties, owners of long lasting companies, ceo’s or other c level people of swiss banks such as UBS or Credit Suisse, or of other important companies as Swisscom, Migros etc, ambassadors, state leaders, scientists etc.
Ladies in those circles have master’s degrees from Zurich Uni, Saint Gallen, Oxbridge. They start career in some important company and then stay at home when they get kids. Hi-so doors are mainly closed for Middle Easterns and Eastern Europeans - not saying thats ok, just stating what I see.
Behavior: ladies dont have open profiles on social networks. They never talk about brands, never mention, or God forbid, tag expensive hotels. Only if someone on a party asks you where you went to holidays, you will say only the name of the country or city. Only if they ask for recommendation of a hotel, you will tell but only if you are alone. Otherwise you say “I will send you few nice places in a message”. No silicon lips, no hair extensions, thats a big no-no and puts a woman directly to the cheap drawer. So - discretion, zero bragging. As they have great education, they are very modern and easy going, they dont pose and their elegance comes from simplicity and effortlessness. They are not stiff, most probably the easiest group to talk to as they are trained to have nice conversations.
Also, as country is so rich, it is really not a big deal to own LV bag or Cartier bracelet. Many teenage girls have those, in high school they become apprentices (dual school system) and as their parents are covering costs of living, it is easy to buy fancy bag with apprentice salary.
