DickiesWomen's Relaxed Cargo Pant

This is exactly what I need for work, but dont you sell them in blue? They come in blue for men.

How is the weight of the fabric? I'm looking to not die out in the heat of the afternoon at work this summer, and still have Long Pants to protect me.

What it the inseam for a size 8? I'm 5'8" and need longs but can't seem to find them

What is the return policy? I love the pants but they run larger than expected.
