## Questions & Answers

**Q: I saw a review that stated these are not fleece lined but product description shows it.. can anyone confirm the fleece lining in this product?**
A: The ones I recieved have a very thin fleece lining it's not what you imagine when you hear fleece. But I have several different brands that are fleece lined and they all are made the same. They are made to go under clothing and not be bulky.

A: Too big for a two year old.

**Q: Where can I find sizing chart? What are the ages/measurements of the garments?**
A: At the bottom/ small, medium, large
