Well it's certainly one way to get your boss to notice you.

Wang Kang left his colleagues stunned when he strolled through the Shanghai office entrance unannounced and began strutting along the corridors in the formidable ensemble.

Hot property: Wang's costume has attracted praise from his boss and compliments from women

But Wang said the effort had been well worth it - with his costume drawing praise from his bosses and compliments from women.
He claimed some had even 'fallen in love' with him because of it.
'They said I am a happy and creative man, and they wanted to know me,' he said.
The main material he used was EVA foam, which was glued onto an aluminium frame.
Soldering irons were used to create the effect of rough iron plates and the whole armour was then painted the colour of aged iron.
After the frame and plates were completed, installed wires, pipes and circuits.
He said: 'I sometimes thought of quitting it, as the project was very time and energy-consuming and I had to do it during my free time.
'I just wanted to share the happiness with friends.
'Life needs passion, and I hoped my armour could trigger their passion for life.'
Wang is determined the first costume - the Mk1 - will be the start of many, and hopes to improve the design so it is lighter and more user-friendly.
The current model weighs 50kg and takes ten minutes to put on.
'I want to accumulate more experience via making the MK1 so I can make the MK2 armour really well,' he said.
