This is a Polo Ralph Lauren button-down shirt, size 150. The material is relatively thin and cool. Material: 100% cotton Measurements taken with the shirt laid flat: 49cm across the chest (underarm to underarm), and 71cm from the collar to the hem. Please use these measurements as a general guide, as they are approximate and taken by a non-professional. This is a used item, worn by a child. There are no noticeable tears, but there is a feeling of wear. Please note that I may have missed something during my inspection. This item has been stored at home, so please understand. I used this shirt for slightly more formal occasions. I hope someone will find it useful.
