For this costume our size chart is the most reliable guide, and I'd encourage you to compare your child's measurements there before choosing. In general for girls' costume sizing, Medium typically fits around ages 8–10, Large around 10–12, and X-Large around 12–14, though body measurements matter more than age since kids grow at different rates. Chest, waist, and height are the key numbers to match against the chart for the best fit.
