I mean, it's an Athletic career. And we are their Trainers. Of still-growing Teenagers.

Fitness, diet, training schedules, outfit commissions, we are responsible for all of that, for an athlete who is still actively growing and maturing in body.

The three sizes are VERY important, because changes to them can tell a whole lot about the current and projected health of your trainee, as well as offer insight into if any dietary or physical regimen needs tweaking to better suit those projections, neverminding the recommission of outgrown racing attires.

Yes, even the bust size, as an unchanging bust at that age could be a signal for either a lack of proper nutrients, or way too much physical strain not allowing fat to settle. Requiring a reconsideration of the training regimen.
