These are Polo Ralph Lauren herringbone pattern trousers. They are popular jogger-style pants. I purchased these, but my child outgrew them before wearing them much. They are chic and stylish pants, suitable for both casual wear and outings. The size is M, 10/12, which is approximately a size 150. They haven't been worn much and are in good condition, but please understand that they have been worn by a child. They have been stored at home, so please refrain from bidding if you are concerned. Also, the actual color may differ slightly depending on your computer or smartphone, but we do not accept returns in such cases. If the photos do not accurately convey the details, I will explain them in the description. I have also thoroughly inspected the item, but there may be oversights... Please understand and acknowledge that this is a used item. I once received a complaint from someone who did not understand that it was a used item and made a claim as if they had purchased a new item. If you have any concerns, please ask questions before bidding. We do not accept any claims after purchase. Please bid with your understanding. If you have any questions, please feel free to ask in the question section. - Design: Herringbone pattern - Color: Black and white stripes - Waistband: Striped elastic waistband - Pockets: With back pockets Thank you for viewing.
