It is really hard to say. In my opinion, I don't think shutter shades are still that popular than before. I always believe that people wear shutter shades for show or pubs. It can not be worn in daily life. Sunglasses which stay in the fashion for years are the representative of real fashion, such as wayfarer of Ray ban. They will never look out of date. Of cause, shutter shades are not out of date today. But I think it just because of their uniqueness. Things that is too out of box enjoy shorter life that the classical ones. Unless there are designers who grant new vitality to shutter shade to make it popular again, I don't think it will still be in vogue. If you think shutter shade is really cool and you are confident to find perfect matches to go with them, absolutely you can buy a pair. Maybe you can be the designer who rebuild it.
