They are quite sheer. They're fine for wearing around the house or to sleep in, but we don't let my daughter wear them outside (and we're not particularly puritanical about our idea of modesty lol, so it's pretty clean). However, they are ideal for a child who sleeps hot, very light and made of soft fabric.
