Lauren Ammermanwrote a review of The North Face Aboutaday Pant - Women's on January 9, 2018
Familiarity: I returned this product before using it
Fit: Runs small
I'd say that the perfect body plan for these pants would be: very narrow hips/butt and very slender legs.
I normally wear a 26(0)/27(2) in pants for reference. The size difference between the XS and S is shocking. I ordered the S/Reg, and the pants were falling off of me, gaping at the waist, with a reasonable thigh area. I returned them for the XS/Reg, and the XS/Reg crotch/inseam was so tight that it was uncomfortable to sit or bend over, and the pants still gaped at the waist by a few inches, and the thighs were also very tight. ,
These pants also have a HUGE bell-bottom leg, and the sizing of the bell-bottom leg stayed consistent across the S and XS, so on the XS the bell-bottom legs looked ridiculous. I will say that the pants were very warm, and the seams/zippers felt sturdy and well-made, so they'd probably be great for skiing if you can get them to fit.
