You look amazing - and the green belt looks good to me. I can imagine you will get tons of use from this sweater. This is how boyfriend sweaters are supposed to look! Can't wait to see the blue sweater too. If the color works, keep both. The fit is great!
The bling is just right to my eye. You can pull it off! Maybe your eye just has to get used to seeing yourself with that much bling? (I adore that tunic, by the way).
As for the short-sleeve sweater, hands down the long sleeve looks better fit-wise, but I do have to wonder if the short-sleeve would work if you sized down? You, of anyone, should be able to rock this type of sweater. I think it's just a size issue. Is there room to size down, or is this already the XS?
