So let me just say, I'm a clothes and shoes snob. But lately I have been on this quiet affordable luxury lane, and I'm so impressed with Old Navy. Their athleisure is especially amazing and for the price it's a no brainer. These sleek tech pants are no exception. I bought every color available in m...y size, and even sized up to a medium because the small was sold out for some colors. THEY ARE THE BEST. THEY are worth all the hype and OLD navy-PLEASE bring these back in every color. I would love to see white, off white, burgundy, dark navy, brown, and every color under the sun. I haven't travelled with them yet but I can already tell that these will be easy to pack, dress up, dress down. FYI im 5'2" and 140, size 6-8 or 28 in jeans, and normally wear a small -small petite in Old NAVY, Gap and BR. I love the fit of the small regular (check the inseam) but easily went to a medium regular for a baggier look, but note that the waist cannot be adjusted. I don't have a curvy figure, so if you have a smaller waist go with your regular size. I also get short lengths in Gap, but not normally petite. For me- as far as length- regular was perfect because i didn't want it to be cropped. Anyway, JUST GET THEM!
