This is a cute, fluffy, and warm sleepwear for babies☆ It's very convenient for preventing babies from getting cold while sleeping and after bath time♪ It's a large vest type, and there are plastic hook buttons on both sides to prevent it from coming undone. By unfastening the left shoulder and both side hook buttons, you can spread the sleepwear open, making it easy to put on and take off the baby while they are lying down! It's easy to put on and take off with the hook buttons, preventing the shoulders and tummy from getting cold◎ You can also use it in strollers when going out on cold days. There is a little bit of dirt. Please check the photos.
