Off the Shoulder Tie Hem Button-Up Top

I was disappointed when I opened the package because nowhere in the description does it mention that it has a metallic gold look to it. I’ve decided to keep it to wear on a cruise with some gold palazzo pants I bought because the style looks cute with the pants. I’m hoping it will look better after it has been washed. The arm length is ridiculously long. I have long arms, but I will definitely need to push the sleeves up. I meant to order a small because of the recommendation to do so, but must have forgot. The medium seems fine. I’m a 34DD and weigh 145, for reference. I typically wear size 8.
