Cardigans of all shapes and sizes are an ideal choice of retro outerwear, whatever the 20th century era you're emulating. This Study Buddy Cardigan by Kensie Girl combines shape and colour to make a perfectly sixties piece of knitwear.
Taking the edge of menswear that was so in vogue in the decade, this longline cardigan is given some edge thanks to its design as a mini dress. A low V-neck feminises the look, while a great shade of golden rod yellow is instantly mid-sixties.
It's available online from ModCloth for $77.99.
