The straps should stay on the shoulders during normal walking and arm movement without needing constant adjustment. The top should also sit close enough around the chest and underarm area that there is no large gap at the sides, while still allowing comfortable movement. With a layered ruffle camisole, check the fit while your child raises her arms and reaches forward, not just while standing still.

Wide-leg pants should fall close to the top of the shoe without sitting under the heel or dragging on the floor. Check the length while your child walks, sits, and goes up a step in the shoes she will normally wear with the outfit. If the hem repeatedly catches under the heel, the pants are too long even if they look fine while she is standing still.

Choose simple underlayers that are close to the child's skin tone or another soft neutral rather than bright or high-contrast colors. Nude, beige, light cream, or other subtle shades are usually less visible under light clothing than dark underwear or colorful prints. This set uses lightweight fabric, and the product specifically notes that lighter shades may work best with simple neutral underlayers if preferred.

Use a gentle wash routine and avoid high heat, which can be harder on ruffles and textured fabric. For this set, machine wash cold with similar colors on a gentle cycle, do not bleach, and hang or lay flat to dry. While the fabric is still slightly damp, gently smooth the ruffles and wide-leg pants back into their natural shape. Use low heat only if needed.
