How we create these measurement: We lay the garment flat on a table. 

Chest measurement is armpit to armpit, then doubled

Length is high point shoulder to elastic

Elastic measurement is side to side, then doubled.  This number has a range from what it is untouched to a gentle stretch. It should sit gently just below or on the band of your bra and NOT BE TIGHT.

We recommend you measure your own garment this way to compare to our chart.

NOTE: due to the spandex in the fabric, it will stretch to a body measurement a couple inches larger than these measurements
