Every fashionista needs a weapon for self defence when taking public transport. Back in the dark ages, we all had a long umbrella. It looks sleek, helps to keep us dry, and thugs away. Plus Rhianna gave it so much publicity.

But with the advancement of technology and style, the humble umbrella is becoming replaced by something smaller, shinier and classier – a cocktail ring.

These Mawi rings have dual function – they look amazing on your fingers and they may come handy should you run into danger.
