I have several pairs of pants from this brand, but this is my first jacket or top, so I wasn’t sure what to expect from sizing. There is a size chart found further down the listing that I’m not sure was there when I placed my order. Anyway, I most often wear a Medium in tops and jackets (36” bust), so that is what I ordered. Turns out I could have worn a Small. The Medium is fine, especially since it can be cinched at the waist, but I believe a Small would have fit as well. The sleeve length is just a little long, but there is enough of a band at the wrist to keep them from falling over my hands. I find the waist to be a little too high for me to be as flattering as it could be. I am 5’4.5” tall with short legs and a longer torso. The fabric on this is super buttery soft and smooth. It is very lightweight, so I’ll only be able to use it in the late Spring and early Fall here in the Mid-Atlantic. It is a quality piece of clothing. This has the best double-zipper I have ever used in my life! It works perfectly every time without struggle. I also love the covered zipper placket at the collar, allowing it to be zipped up fully without scratching your neck or chin. The Ivory color is lovely. I’ve included several photos of me wearing it various ways as well as a few with a tape measure to more accurately show the size Medium.
