" sexy pictures of themselves in bed, or in other positions" - in most cases its fake😊 This pics shows a bit another qualities of that ladies than hotness))

"pictures that try to show some class, nice gowns, diamonds, champagne etc" - by the way... many Russian women simply have taste. Almost sure you can't see the difference between cheep clothes and very expensive, bijouterie and diamonds😊 If you about furs, its a tradition to have them (every second woman has a mink coat just because its a thing a woman"must have" - and again you hardly can see costs it 2000USD or 60000USD) Like in USSR when woman was able to dish up a "kings" table almost from nothing.
Many women under 30 have parents around 50 who run own business. Its a tradition when parents pay not only for education, but also buy wear, cars and apartments, but this ladies hardly would look for a partner on dating sites.
