MAC Cosmetics have set up their senior artists on twitter for micro blogging during New York fashion week and fashion weeks in other cities. If you look down the right sidebar a bit (look below the blogroll), you will see that I have added a widget that will run a feed of their tweets. Note that not all will be twittering from every city, so you might see some blanks. Also there is the Beauty Blog Network fashion week widget, which will run a feed of headlines from network members pertaining to fashion week throughout the Month of September.
Also, if you would like to follow Beauty and Fashion Tech on twitter, I run headline feed updates through the account Carleenp.
