My gf hosts friends at home while barefoot but with hosiery. It embarres me. What do you think?

Friends would come home.Sometimes even people we meet the first time. She wears jeans and at her feet just nylons, even the reinforced toe ones, sometimes dark, mostly barefoot at times with sandals. I see guys staring at times there, I hate it. I am attracted to women feet myself and I understand how nylon feet can be sensual, y with the transparency and all, but to me it's weird and intimate to share with others who sometimes do look at that detail. And I don't dare telling her. And I always thought women hated that look, that's why they rarely wear hosiery with sandals! She's not shy at all about it, seams and all. If at least she wore regular white socks. What do you think?
