FROGG TOGGSWomen's Standard Ultra-Lite2 2-Layer Waterproof Breathable Rain Jacket

How accurate is the sizing? i ordered a large in a different frog togg, after measuring myself, and found it to be about 4 inches too small!!! :(

Is the jacket lined?

its like paper dont look waterproof r you sure it is

I normally wear a size 4, but based on the size chart (bust size), I would need a medium. I ordered a large; it is huge; should i order a medium?
