NEW YORK, Sep 11, 2012/ — Nowadays, fashion week invitations are through email or Fashion GPS. Gone are the days when we anxiously wait on our mailboxes to receive hard copy invitations which we meticulously go through not just to create our fashion week calendar but which goes to the bin after its use or we keep simply because they are works of art in their own right. The Marimekko invitation for Spring 2013 falls in the category of “must-keep.” Made of fabric in bright geometrical prints, it can function as a sleeve for the mini tablets in the market.
