For example, you can dive into its depths if you need to avoid someone, use it to keep people out of your personal space on public transport, or even hide your flats in there so the office think you wear your heels all day like some kind of Superwoman.
In fact, it's got so many great uses that sometimes we forget to put the essentials in there... but that's where we come in!
1. Lipstick - who knows who you might bump into?!
2, Concealer - because spots always turn up at inappropriate times
3. Nail Polish - the day you forget yours is the day it will chip!
4. Umbrella - we live in England, after all...
5. Hairbrush - see above point.
