This is a 3-piece set from GLAZOS, including a jacket, pants, and shirt. I believe it's rare to find a junior's suit in size 170cm. (I selected 160cm as there was no option for 170cm). I've worn it a few times, but there are no noticeable stains or marks. (I apologize if I missed anything). The shirt has been washed in a washing machine. I think it can be worn without ironing. Please understand that this is a used item before purchasing.
