The SM post has irked me enough to comment.
Many privileged, white, middle class instamums have piled on with messages espousing how proud they are of her. Even lesser known instamums have commented saying how proud they are of the brand which is just bizarre!
I agree with some of the criticism of the brand. It does come across as smug but that's because of its heavy association with the London instamum set who adopted it as their go to uniform. Many of whom I suspect are gifted the jumpers in the first place. They then try to sell them to their follows as a way to be part of the mum tribe.
I don't doubt the good that donating part of the profit to the charity does but the ubiquity of the brand on instagram is off putting and personally I would feel like I'm following the crowd wearing one of their jumpers as I would if I wore any other well known branded item instead of being an individual.
The sweeping statement about forums is so tone deaf. I've used forums and have come across some really kind and helpful people. SM doesn't realise that people who buy from her are also forum users as well.
