These are TINY! My 4 year old put it on and it was so short, then after it was washed it got even smaller! It literally fits my 1 year old as a dress at this point. Size up like three sizes! The material is not stretchy at all which is to be expected, but it is very thin and you can see through the material if you hold it up to the light. It's not something I would buy again or recommend.
