We have blue mermaid foil leggings for 3 little girls. The length was almost as expected, but a bit long on one pair - we just rolled up the top. We've washed them a few times - no scratch marks. Seen from the wrong side of the fabric, they seem to become more transparent with each wash, but are not yet visible from the front (2-3 washes). None of the kids crawl but I think if they did the knees would wear out quickly as the material is thin. Overall the kids loved them, they served the purpose of making kids with mermaid fever happy, so we're happy too.
