I bought the cap in size 56. We have used them throughout the winter a lot and she was washed several times - without any problems. The hat is very flexible, which is why they even now fits perfectly. What you do not recognize in the picture soooo good, that is up some "survives". My Little so looks a bit like a little dwarf, zuckersüss! :-) As his head circumference of these days but tidy increases, we will probably soon but a need to establish greater after four months, so that the ears remain covered! Absolute buy recommendation!
