I bought a size 4, which is what my daughter takes in clothes. She is tall, so sometimes we need a 5 just for the length. These pants are 1-2 FEET too long! I am 5'7' and they almost work for my legs. Also, the pants come up very high on her chest (not waist); it that usual for snow pants??? Unless a neighbor can use them, I will be returning them immediately. I gave it 2 stars because they seemed to be well made.
