A sleeveless vest should sit smoothly across the shoulders and chest without pulling at the V-neck or creating large gaps around the armholes. Have your child raise her arms, reach forward, and sit down while checking the fit. If the armholes dig into the underarms or the front of the vest pulls open during normal movement, the size may be too small. If the shoulders slide outward or the armholes gape significantly, it may be too large.

Use a gentle wash cycle and avoid high heat. After washing, gently straighten the skirt and guide the pleats back into their natural folds while the fabric is still slightly damp. Hang or lay the skirt flat to dry rather than using high heat in the dryer. If light ironing is needed, use low heat and follow the existing pleat lines instead of pressing across them.

Choose a lightweight, close-fitting layer that sits smoothly under the vest. A simple long-sleeve tee, slim knit top, or lightweight blouse can add coverage without creating excess fabric around the armholes and waist. Avoid very oversized sleeves or heavy ruffles if you want to keep the tailored shape of the vest visible.

It can be useful, especially for children who will be running, climbing, sitting on the floor, or moving around a lot. Lightweight fitted shorts can provide extra coverage without changing the look of the skirt, as long as they do not bunch at the waistband or show below the hem. Whether they are needed depends on the child's comfort and how active the day will be.
