Red: YLG145-155 Blue-violet: YXL155-165 ※Looks blue in the photo, but it's blue-violet. My child used these for mini-basketball practice for 2 years. They are slim, so they should fit children one size smaller as well. My son, who is 145cm tall, wore both. How about them for a change of clothes? The print on the front of the third photo is peeling off, so I'll include this sleeveless shirt as well (^^) Size YLG They show signs of use, but can still be worn. Please consider purchasing if you understand that these are used items.
