I bought these undershirts to use for my 3 year old daughter as pajama tops during the summer. They are perfect for that- lightweight, sleeveless, and breathable. I love that they are white and match any bottoms, and they have a cute little bow detail at the top. The only reason that I marked it 4 stars instead of 5 is that one of them came with a strange black mark on the top of the strap- it almost looked like a sharpie mark. Since these are just pajamas, I don't mind too much, but it does seem like a quality control issue.
