Description Thunderpants 90% organic cotton/10% spandex fabric is sturdy, very stretchy, and has great retention to give our garments just enough stretch and bounce back. It helps the undies to stay up and on, and the other garments to keep their shape without sagging or bagging. We use the same soft organic cotton blend to cut our binding into a wide strip instead of using elastic so their is never any irritating elastic against your skin. All the garments are made locally and lovingly in Portland, OR. Bra Size Underbust (Inches) Small 32 28-29 Medium 34 30-31 Large 36 32-33 X Large 38 34-35 2X Large 40 36-37
