I am embroiled in an argument with my mum and aunt (her sister). Both in their 50s.
I had some photos taken yesterday for a hedge fund website. I was carrying a black leather handbag (this one if it matters!) I bought it when I returned after maternity leave to feel more professional and put together. It's waterproof smart, and fits my laptop, A4 files and everything I need without being monstrous or fashion victim-y. I have seen other women in the City with the exact same bag.
They told me it was unprofessional and I should carry a laptop style briefcase - the kind that is given out for free at conferences with a logo on the side.
They said men associate women with shopping and statement handbags are therefore unprofessional because they will make clients think you're some sort of label-obsessed airhead. A huge shiny laptop briefcase with a bank logo (not even our own logo!) apparently sends the right image of a confident professional woman. If I don't want to carry a briefcase apparently no bag at all is a better alternative than my black leather handbag 
I think they are being U and stuck in some 80s time warp, thinking we have to out macho the men to be taken seriously. They think I am U for not listening to their years of experience.
FWIW I did my first investment banking internship in 2002 and have worked full time in the City since 2008 in a formal office environment so not exactly a neophyte but apparently as they are 25 years older they will always know better.
AIBU?
