Hello @Daniela
welcome to the community. I love what you did to the case and I definitely agree that womens clothes are not always designed to carry modern smartphones:) I am also using the popsocket as I find FP5 definitely too big for my palm;-)
but there are some other flipcases for FP5 available, from some sellers on Amazon, from Anna Treurniet, from CaseOnline, or from Noreve, the latter though has been criticized on the forum for their take on FP4.
PS. I cant see any other flipcases with two holes for a lanyard though:)
