Would it be very, very wrong to use an Hermes charm/key chain on a Louis Vuitton bag? I'd love to introduce my mom to Hermes (for Mother's Day?) with the Eiffel Tower key chain or perhaps a twilly. is this terrible? would she be frowned on by an SA? here is the LV bag in question, the red epi alma tia! i worship at the alter of Hermes. also, are the key chains tricky to use? how does the clasp work?
