White is the hardest colour to get right in knitwear and the most rewarding when you do. A good white cardigan sits somewhere between layering piece and actual outfit, which is why the right one gets worn constantly and the wrong one sits folded and slightly disappointing at the back of a shelf. We have been genuinely particular about which ones make it here. Weight matters. A cardigan that is too thin looks cheap immediately. One that is too heavy becomes unwearable for half the year. The ones we have chosen hit that sweet spot where the fabric has real presence without being oppressive. We are also interested in how they finish. Buttons that feel substantial, ribbing that holds its shape after washing, a length that works over both jeans and a dress. White is unforgiving in that way. Every detail reads. These are the cardigans that passed every test we put them through, the ones we actually reach for on the mornings when we want to look pulled together without overthinking it. A brilliant white cardigan is not a basic. It is a foundation.
