Nude knickers are basics every woman needs in her underwear drawer. Building on that essential is this pack of three bikini briefs, in solids and prints, in various shades of beige. A bikini brief is a panty that sits low on the hips 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.
