DickiesEDS Signature DK125 Women's Mid-Rise, Tapered Leg Pull-on Pant

Can I return these if they don't fit? Is there a charge to ship back or a restocking fee?

I’m 4’11 105 lbs should I get the xs petite or xxs?

Do these pants have a drawstring? The description states drawstring, but the picture doesn't show one.

Do these come in a khaki color
