A single shade of blue printed with lighter and darker tonal florals creates depth without introducing new colors. Shift dresses in tonal floral work because they are comfortable and unfussy while still looking considered. The all-blue palette makes these dresses easy to style since nothing in your closet will clash with them. The floral pattern lifts the simplicity of the shift silhouette so the dress reads as intentional rather than just basic. These work as everyday dresses that happen to be pretty. The tonal approach means you get visual interest without commitment.
