I ordered a size up M (usually S) to wear as a vest. M offers a relaxed look when layering with a collar top or a t-shirt. The length sits about two inches below the waist. If you prefer the look on your model after layering, I would say to stick with your usual size as the sweater is soft and stretchy.

I ordered the gray color and loved it. The color is not to dark. The weight of the sweater vest is perfect and I loved the cut and the button features. There is some stretch in the material but not overly stretchy; I think it would hold shape after washing. I ordered my usual size medium and had room to wear a button down under it. Unfortunately, I had to return the sweater due to the length. This is definitely cropped which I do not like. The description states 22 Inches in length (shorter than I like but I thought it would work if I wore something underneath), but the one I received measures 18 inches from the top of the shoulder to the bottom of the hem. The picture doesn't accurately represent the the location of where the sweater would hit; on me it was 2-3 inches above my navel. Due to the length, I was unable to style it in a relaxed classic fashion so back it goes.
