Unknown size Armando Martillo Dress Pants for baby boys

I am unsure what size these are as the tag is totally rubbed out, but if I had to guess between 12-18 months. These suit/formal pants are for toddlers and are in used condition- has signs of wash wear such as fading/pilling. Sorry for the lint in the pic, will be laundered and lint rolled prior to shipping.
