It's a quality product. The 15-year-old likes it and won't say anything else. We measured incorrectly first and had to do an exchange. Here's the sizing tip the representative sent me:
To measure for her bra size, you can use the following instructions while wearing an unlined or lightly lined bra style:
For her band measurement: Measure snugly around her ribcage, directly under her bust. Add 2” to her underbust measurement, & round up to the closest even number.
Example: 31” + 2” = 33", rounded up to 34” Band size = 34
For her cup measurement: Wrap the measuring tape snugly around the fullest part of her bust. Compare her full bust measurement to your original ribcage measurement (the smallest number). For every inch difference, add a cup size. US cup sizes go in order of A, B, C, D, DD, E, F, G etc.
Example: 31” ribcage measurement & 36” across-bust measurement = 5” difference , Go up 5 cup sizes. Cup size = 34DD
