Retro... Or vintage?

Am I the only one who is confused about that? Where does Vintage stop and Retro start? I am a very big fan of, as I like to call it, cheesy-oldfashioned. Whether that is vintage or retro. Like this fabric. It's not old, it's from some 2008 collection, but it looks so... Eh... Groovy?

The book will be available in my Etsy shop later today... Just in case anyone is interested...
