These mock neck French terry bamboo are next level! We live in a very warm state, but still get plenty of use out of this set! We love wearing it to lounge inside in and it’s perfect for outdoor play once we’re back in the 70’s. They are SO soft and the colors on this- pictures don’t even do it justice. My girl is almost 12mo and I did get her the 12-18, the 6-12 would have fit better currently, but this 12-18 she’ll get a whole year if not longer out of!
