The slip dress has a reputation problem. People assume it only works at night, or that it needs a lot of scaffolding around it to function in daylight. We disagree entirely. The right slip dress, in the right fabric and cut, is one of the most quietly capable things you can own. It layers over a fitted long sleeve for autumn mornings. It goes straight to a rooftop bar without you changing a single thing. It works at a wedding and at a garden lunch and on a Sunday when you simply want to look put together without thinking too hard about it. The key is fabric weight and structure. A slip that has some body to it rather than clinging desperately to everything is the one that actually earns daily wear. We have been pulling together our favourites specifically for daytime, the ones that photograph well in sunlight, that move properly, and that do not require a plan B outfit waiting at home. These slip dresses are genuinely useful. That is the highest compliment we know how to give.
