Am I supposed to wear something nicer
Yes, yes, you're a mother now. You have to shun all your normal clothes and buy dresses just for the school run, please ensure they are as frumpy and mumsy as you can find, the Bon marche catalogue should be your first port of call.
Throw our your joggers, burn your hoodies, cut up your skinnies, give your biker jackets to charity, embrace the frump. 🤣
