A nautical set of knickers in star, polka and solid patterns will be a fantastic addition to your underwear collection. Made from superior cotton stretch and accented with dainty details, these bikini briefs are perfect to wear under dark garments for all-day comfort. 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 thus are long-lasting. M&S uses latex-free elastics that are gentle on your skin and provide great comfort.
