NWT. US size 10 but fits like a US size 6 ( size small). I'm listing as both sizes for search purposes only but I only have one suit in size US 10. See measurements below for help. I also have the matching Goldbergh ski goggles, fanny pack, helmet and pink baselayers listed. ***MEASUREMENTS*** -exterior measurements Pit to pit laying flat: roughly 19 inches from outside (I would deduct 1.5 inches for true pit to pit which puts it at 17.5 inches) - exterior measurements of Hips across the crotch area(widest part): roughly 18 inches (I would deduct 1.5 inches for true hips which puts it at 16.5 inc) keep in mind there is actually a slight elasticity to this material. it is a bit forgiving, not so so stiff! very comfortable to ski in. (The white on the zippers is paper protective covers). Goldbergh's jumpsuit features an eye-catching colorblock design and zip pockets at the chest and waist. This down one-piece is finished with a large logo belt. Hooded Stand neck Long sleeves with zip cuffs Zip pockets Logo belt 74% polyamide/26% elastane 90/10 duck down Primaloft padding (The first picture isn't mine and the colors are a bit different on the actual ski suit. I attached it so you see what it looks like on the slopes) I have lots of Ski items listed in my closet from Goldbergh, Cordova, Perfect Moment, Moon Boots and Bogner.
