The size is 170cm. Please note that the size listed in the product name may differ because children's clothing is only labeled up to 160cm. Worn about 2-3 times. I bought different sizes, but my preferences changed, and I'm selling it because it's outgrown without being worn. Ralph Lauren long-sleeved shirt with a blue-based check pattern made of natural stretch material. #Ralph Lauren #RalphLauren #170cm #CheckPattern #NaturalStretch #Blue系 (Blue-based) #LongSleeves #Shirt Thank you for viewing. Although it's a near-new item, please refrain from purchasing if you are sensitive to details, as it has been stored at home and inspected by an amateur.
