This is a kimono for a 3-year-old's Shichi-Go-San (Girls). Some of the thread on the string has come off, so it has been tied. Half of it remains and won't come undone, so it's still wearable as is, but it might be safer to sew it back on. (See photo 4) If you'd like, I'll also include a hair ornament and tabi-style socks as a bonus!
