Checked patterns on navy shirt dresses add visual interest without departing from casual. A check reads as inherently informal which suits the shirt dress format perfectly. The pattern also adds dimension which keeps a simple silhouette from reading as boring. Navy as a base colour on a checked pattern means the check remains readable without becoming visually complicated. Gingham and larger checks work well. Small tight checks can read as busy. The checked pattern also means the dress works across seasons and occasions. Wear it casually with minimal styling or dress it up with appropriate accessories. The check provides enough visual interest that you can keep everything else quiet. These are the pieces that feel youthful without being novelty pieces. The pattern is classic and the colour is versatile.
