(Location: Chicago, N.Y.; Name: unknown-mystery doggo 🙊; Photographer: Amanda Z.) Who is this mysterious dog (and stylish dog dad) speeding down Chicago's Michigan Ave six years ago? Nobody knows, but one intrepid TSF contributor dug this out of the photographic archives because this fashion flashback is too badass too miss. This confident pooch rocks his safe and stylish helmet and eyewear, with a bold, traffic-stopping mustard yellow vest to complete his look. That's so fetch, mystery Windy City dog. That's.So.Fetch. . . . . .
