A midi dress in a textured fabric like cable knit, jacquard, or subtle brocade brings visual interest that reads as elevated rather than busy. Texture adds dimension that solid colors sometimes lack while keeping the overall effect formal and appropriate. A textured midi dress works particularly well in darker colors where the pattern shows up clearly. The texture also adds warmth which is practical for indoor church celebrations. Avoid textures that are too bold or novelty prints because those read as costume rather than appropriate. What you want is subtle texture that adds depth and keeps things interesting. A textured midi dress demonstrates that you can dress appropriately for an important occasion while still choosing something visually compelling.
