I am 5 ft, 97-100 lbs, 64 yrs, a grandma. I got the xs and they fit great.
I would have preferred 8 in inseam but the 6 in is OK.
I started out with 3 pair, liked so well I got other colors.
I soon realized I really liked them so I got more. I now have 2 pair each of 6 colors. Half of them I wear for walking, hiking, running and the other half for daily wear. I remove the belts, don't use at all. I never snap or zip them, just slip on and off. My favorite thing is how quickly they dry. I also like all the pockets. The colors are really pretty. I wash and hang to dry.
I believe Columbia has discontinued this style..too bad...but I 'm set!
