I bought this for my 8-year-old son's piano recital, but it was too small to wear, so it's unused. The fabric is sturdy and the shape is crisp, making it look very cool. How about for formal occasions, recitals, or graduation ceremonies? Beige cotton vest (reversible) and shorts set ★The tag says 7-8 years old, but because it's cotton, it has almost no stretch. I think it's more suitable for 5-6 year olds. The size is probably around 110-120cm. - Brand: TACTON JUNIORS - Size: Approximately 7-8 years old ★Length: 36cm Chest circumference: 70cm ★Waist: 60cm - Style: Vest (reversible) and shorts set - Color: Beige - Material: Cotton ※This was a gift and has never been worn.
