Not that I have been attending any special events of late but I have noticed in posts here, as well as pictures in high society magazines that women will attend special functions with their Hermes when it's not a Hermes event. Be it Chanel, Gucci, Prada, Dior etc. Of course you are free to choose what bag to bring but it set me thinking. If you are a VVIP of the other brands as well, wouldn't your SA or store manager of those brands prefer you to wear one of their bags? Is it not a bag faux pas, ignoring the need to wear a bag that represents that brand at such events? I'd thought it's only out of respect that you'd want to do that? I speak this from experience - Toyota was my client when I was still working. And it's very clear that we have to respect the company's ethos and my bosses had to ditch their other cars at home and only drive their Toyotas to see the bosses at the Toyota offices. Maybe cars and bags are 2 completely different and cannot be compared.
