The sizing is based on someone who is 173cm tall and weighs 58kg! All jeans are size M! The JUNGLE STORM jeans (1st and 2nd photos) are light blue and blue denim, and the waist was a little big. They don't seem to be sold anymore, and I think they were about 3000 yen each. The indigo blue ones from monomart were just the right fit! According to the official [recommended sizes]: Size XS: Height up to 160cm Size S: Height 161cm - 165cm Size M: Height 166cm - 170cm Size L: Height 171cm and up! They are sold on ZOZOTOWN and I bought them for about 2000 yen. Please feel free to ask any questions in the comments. This item is not returnable. Thank you for your understanding.
