Haha, I always think the same about Mumsnetters dressing like Princess Kate.
Any threads about wedding guest attire or office-appropriate clothing, in particular, makes me imagine an army of furious Mumsnetters in court shoes, jewel-toned a-line coat dresses and bouncy blow-dries, all clutching their pearls at anyone who goes to a wedding in a jumpsuit or wears Doc Martens at work. Kids all in Boden, teens in Jack Wills, not a supermarket branded Paw Patrol t-shirt, Adidas hoodie or Primark crop top in sight.
