Men’s Lalabu baby-wearing shirt! Was only used twice! There are some white chalky-looking spots on the shirt that appeared after the one time we washed it. I was able to remove most of them with a wet washcloth, but there are still some patchy faint marks on the shirt. “The Lalabu Dad Shirt is the first babywearing shirt designed exclusively for dads.
