difference between 90s and 2000s fashion and style is in 90s people like to wear less skinny high waisted jean  but in 2000s people prefer low waisted ankel cut skinny jeans

If we talk about shirts in 90s people wear more loose baggy fitted type shirts with less prints and there clothing material was thicker like the prefer velvet cotterise  denim n all 

but in 2000s people wear skinny or slim fit shirts with light clothing material  like cotton mix etc which looks more good according to me. but what ever your choise is they both looks good in a specific manner  and remember style is more about personality .
