This is based on Derby\'s original kit from 1884, the differences include subtle adidas stripes on the shirt and socks while the socks are hooped. On the shirt there is a adidas logo and the Derby ram. Finally on the back of the shirt beneath the collar there is a part of Derby\'s coat of arms.
I like the use of the subtle badges/3 stripes. I think possibly the stripes would work better if they were just on the top of the shoulders (similar to Derby's kit season just finished) and leave the sleeves plain.
