Overalls purchased from H&M. The size is a bit tricky, but it's approximately a size that can be worn by a 1.5 to 2-year-old. They're made of denim but are soft and lightweight. The shoulder straps can be adjusted in two stages with snap buttons, and there are also snap buttons around the waist, making them easy to put on and take off. They're really cute, so I hope you'll dress your child in them!
