I am 5”5, 112lbs, thin frame. I am 28” at my belly button, 26” at the small of my waist.. The size 2 fit me perfectly. These are probably the first dress pants I have ever owned that do not make my derrière look flat (which is the direction it leans.) They sit right at my belly button, require no additional fittings, look so cute with a body suit, and also with flowy tops. I can wear them at home while sitting legs crossed, and could imagine a long flight with them as well. They appear to me to stay wrinkle-free, which we all love. They are great, and are now a staple in my closet.
