  The Dress That Turns into a Coca Cola Machine 

    This specially designed dress looks like a normal dress，but if you unfold it and cover yourself，you may look like a Coca Cola vending machine（自动售货机）. Because there are many vending machines like that on the street，it must be easy for you to hide．If you feel that someone is following you or there is some danger，you can disappear within five seconds．But don't use it to scare your classmates．That'll be rude.
                                  

    The M-Dress is a nice black dress．It is also a mobile phone．It accepts a standard SIM card and allows the wearer to receive calls without carrying an actual(真实的) phone in their pocket or purse．You just need to bring your hand to your ear when you want to answer a phone call．When you finish talking and release your hand，the call will close．It is fashionable and useful．But it will certainly be an embarrassing moment when your dress rings in public．
