This is a combination undergarment, size 50-60. The fasteners on the parts that touch the skin, which are not visible, are only ties. It looks like there are no noticeable stains. However, since it was used when the baby was young, there is a possibility of stains that won't come out, so I've set the condition to this. I think it wasn't used that many times because I rotated through a lot of undergarments. I'd appreciate it if you could think of it as a bonus if there are no stains!
