We've all noticed the shoulder loops on your jacket and wondered what they are for and now we know why... Finally!

Honestly, we've never seen anyone use them properly but maybe now people will and it would be handy if you have lots of bags or a sneaky shoulder strap that keeps slipping off.

The loops are to hold your bag in place and to prevent it from sliding off your shoulder.

Our minds are blown after years of wondering!

Francheska took to Twitter to share the mind-blowing news!
