Do you always wonder if you should order up in size just in case the company's size chart is off? I do, and I wish I had not. I am 5'9", 175, strong/ muscular skier build with a large 38 D chest (FYI I wear sz 10 and sometimes 12 pants and XL shirts due to strong/wide shoulders/large chest- I usually fit into Large womens ski pants and either L or XL jackets) I should have ordered a Large.. but I ordered an XL- they are super big. (and long inseam)... I am still keeping them since I got them on sale- but just in case you also find yourself in this predicament- do NOT order a size up. I still LOVE my new bibs, they are warm, waterproof, stylish, and comfy. The tan color reminds me of Carhartts and looks great with my dark brown jacket. I just wish I ordered a large ;( since Spyder's size chart seems true to size). My bad.
