According to the group of people who officially call things "vintage", clothes and accessories from the 90s can now officially be called "vintage". I don't know how you get the authority to call things the way you see them, but they have this power. So, this means all the old people from the 80's now are joined by all the old people from the 90's. Wait till they start calling your music "oldies".

According to Catwalk Queen, Patricia Dillon, the Divisional Leader of Design and Applied Arts at the University of Wolverhampton:

"For something to be classed as Vintage it needs to be of sufficient quality of design and creative execution for it to stand the test of time and be relevant and desirable to future discerning generations. The 90s are now officially classified as Vintage because we are two decades on and a new generation is starting to discover and enjoy the creative fruits of musicians, designers, artists and film makers who delivered their ideas 20 years ago."

This means that items that were popular in the 90s, like grunge, big shoes, neon, babydoll dresses, neo-preppy, and Euro-designer monograms are back in a big way.
