The right knickers make a difference to how an outfit sits and feels and we’re not embarrassed to talk about that. Whether you need seamless for fitted trousers, high waisted for dresses, something comfortable for a long day, or something that looks genuinely nice, there are options here. We’ve pulled together the picks across function and form because both things matter and you shouldn’t have to choose between them. These are the ones we’d actually recommend to a friend.
