Stripes and dots might seem like poles apart but not in this knicker set from M&S. This classic monochrome set features a pair of polka, a pair of solids and one striper midi with dainty lace details on the waistband. A midi is a panty that sits right under the waist with full bottom coverage. What's great about these undergarments is that they resist pilling and colour fade and hence are long-lasting. M&S uses latex-free elastics that are gentle on your skin and provide great comfort.
