The sizing is way out, I had to re-purchase twice. My daughter is a tall, medium built 8 year old so I initially bought age 12, which was far too tight. The age 14 blouse was a better fit, but not much growing room so then we tried the age 16 blouse, which is a bit too long. This is not marketed as a ‘slim fit' like other options, so I am surprised at how tight it is. Girls need room to breathe, move and grow!
