we can look for the rules of fashion, here go 7
1) no additive property, the sum of fashion things does not guarantee a fashion result. in fact the key of fashion is Combine, not Sum.
wear pretty sport clothes with pretty high heels is not fashion result.
2) follow the mode and be a kind of ad-man is not the same. Wear a lot of clothes with big brand´s icons is not fashion, maybe only show your purchasing power.
A bag with the icon of the brand very big, you pay and also you do publicity for them
3) black and white always combine good, but not white socks with formal shoes!!!!!!!!!!!!!!!!! puaj puaj
4) trousers always under navel, never up, do you want be Obelix?
5) A fashion thing begins to die when that thing begins to be used massively, when all people wear the same thing, when even kids and your grandparents have one of those fashionable things.
for example the glasses in the style of Audrey Hepburn in Breakfast at Tiffany's are a good example. you can change the colour, white, pink, red whatever you want, but that thing is dead.
6) Exotic things are always susceptible to becoming fashionable. If you travel out of your country, import exotic clothes.
the cut mandarin collar shirts, is always chic (out of China)
7) there is a kind of clothes that you only can wear in party. for example party high heels (fucking shining) can blind the people if you wear in the day.
