i don't follow any of the insta-mums, but do/did follow some fashion bloggers, and I think the big issue here is the same.
IMVHO, the reason people started following fashion bloggers because they represented something very, very different to the magazines i.e. people with real jobs with dress requirements, with real budgets (some of them even wore the same stuff twice
), and without clothes being pinned, fancy lighting and photoshop. The copy was also uninfluenced by advertisers, so you'd find out if something shrank, or if heels snapped off shoes.
However, the brands got in on the act, and now a good whack of the fashion bloggers are flogging stuff they're paid to, often via professional shoots and press days, and can't bite the hands that feed them.
All props to them - if you can get paid to do something you love, why wouldn't you? But since the objectivity and "realness" has gone, they offer me nothing different to the magazines, and the models are better there
