I have this top in several colors, & I have the old style in several colors. The M is a perfect fit for me at 165lbs & 5'6" in both styles. Most of my tops are Regular, but then I started getting the Tall for a longer fit to wear with leggings, the petite for a shorter top with wide-leg pants. The... old style that had a back pleat or a cut-out was extremely flattering being longer in the back. It really was perfect. While the new style is still the best top for me that you sell, it really is not flattering being longer in the front. Who would ever come up with such a terrible design. It's almost like the pattern got reversed! The back should always be longer!!! Shorter in front is more flattering on everyone, I really like covering my rear when I wear leggings & wish Athleta offered a version of With Ease that did that. Other than the quirky design, the With Ease is absolutely the most comfortable of your tops with nice fabric, not too heavy or clingy. I wear it all year around.
