Jess Cartner-Morley on fashion: Want a style update? Pull your socks up!

You don’t have to get on board with this easy, fun and cheap fashion development … but a bare ankle is no longer cute

If you get food in your teeth at dinner, you want someone to let you know, right? Of course you do. It is so annoying to realise on a bathroom break, after pudding, that for the past two hours you have been unwittingly showing the remains of your starter with every smile.

However. It is also undeniably the case that when someone does the right thing, letting you know that you might want to check a mirror, that moment can be awkward. Especially if you don’t know each other well, the spinach-eater might feel embarrassed and flustered and even, irrationally, a bit cross.
