These are excellent. The only issue that I see, I ordered a F1 for my girls. According to the chart, they are smack in the middle for the F1 sizing. The only thing, it did not account for a bigger bust size. So I have an F1 with a D-cup, so needless to say the top does not close fully.
You might want to included that in the chart for future purposes, or allow to choose the F1 pants and a F2 top?
Either way, I stand by my purchase and a wonderful product.
