Oliver Spencer's fishtail trousers are so-called because of the v-shaped cut in the rear of the waistband, which creates a more comfortable fit. If you’re looking for a modern flat-fronted trouser with a gradual taper from the mid-thigh that will go with virtually everything you have in your wardrobe, you can call halt on the search now. This season, we've cut them in a midweight organic cotton twill for a lightweight feel, elegant shape and supreme comfort.
