I don't know who is designing women's pants for The North Face, but they freaking have it RIGHT! This is my second pair of TNF pants, and they seem to be the only women's brand that are so flattering to an athletic build. I hope they don't change. If you want to compare sizing, I just ordered the 4Reg (I usually like 34" inseams), and they are PERFECT. I'm 5'5", have muscular thighs (read "big" ie don't fit into the ridiculous pencil pants), waist is 27" and, hips (with no saddle bags) and 36" hips. They don't accentuate my defects, only look great! If you are about my dimensions, you'll love these.
