Very pretty, nice quality but it is NOT 'one size fits all' and it does NOT fit a large busted woman or an X large...it is, at best, a fit to a size Large if you do Not have a big bust or broad shoulders.  I think it would fit up to a Medium very well if you want it to fit you like it fits the model, loose and comfortable...and no way anyone could wear it as a dress unless you don't mind showing your jewels, it is a nice length tunic top.  I have 44D bust and had to return it, I got it on, but it crushed me flat and it was too tight in shoulders and arms also....depending on the top I usually wear a large or x-large in US sizes.  But if you are the right size, it is a beautiful top, made well and nice, soft, opaque material.
