I ordered size 4 for my daughter who was due to start playing soccer this year but got 6x instead. We're not making T-Ball anymore this year so we're keeping them and hopefully they'll fit next year. The material is quite thin and if I hold it up to the light I can see through it. These are cheaper pants and one of the few I could find even in a girls size 4 but still poorer quality than the cheaper pants I bought for my son.
