A slip dress is simultaneously the simplest and the most endlessly stylish thing you can own. The format has been around for decades and it refuses to date because the simplicity of it is just correct. Wear it alone. Layer it over a tee. Put a blazer over it. Add a chunky knit in autumn. The slip dress works in every configuration and in every season. We’ve pulled together the ones with the right weight and the right cut to actually flatter rather than just hang. Because there is a significant difference.
