This dress is so comfortable and very well-made and forgiving! I used my largest measurement, my shoulders, to select a size. The top layer is soft and stretchy, but the under-dress is a light cotton or poplin-like material which does not stretch. There is quite a bit of volume in the skirt and, on me, it poofs out, making an unflatteringly wide silhouette. Other people's pictures look so cute and not poofy, so it might be my shape. I considered keeping it as at-home wear since it is that cozy but I will check out Minibee clothes for other daily wear.
