Vintage grid dress

Vintage navy blue cotton dress with a checker / grid pattern. Marked size 10, pictured on a size small for reference. Suepr cute with pleated details at the waist, buttons on the side, and one side pocket. Feels like a pinafore dress - I've worn this without a top underneath, but the arm holes go quite low so it's great for layering shirts and sweaters underneath! When laid flat, measures about 42" long, and chest (under armpit) measures about 19" across. Missing 1 button on the side (as pictured).
