Baby undershirts, tank tops, set of 4. Two size 60 and two size 70. These can be worn year-round, in summer and winter. As you can see in the fourth photo, the size 60 and 70 don't seem to differ much. I bought these but only wore them a few times, and my child has already outgrown them. If anyone would like to use them, please do! The crocodile pattern ones were worn relatively often, but they are still wearable! There are wrinkles, but they should become very clean with ironing. I don't see any noticeable stains, fuzzing, or fading of the patterns. However, please refrain from purchasing if you are looking for a perfect item, as these are used. Please purchase only if you understand this.
