Very cute casual tee.  I ordered up one size and it is loose, but not like a shapeless sack.  The lace detail on shoulders and back is very cute, and not scratchy on the skin. If you are a large chested woman, the back lace may be a bit low and show your bra, if the band is one of the wide ones. I am NOT large chested and the bra never peeked out the back for me.  The fabric is thin, but the green was not see thru. I don't think it was too thin, it fits the casual style of the shirt. I probably will order another color or two.
