One-Shoulder Long Sleeve Jersey Dress

I love the look of this dress and was pleased to open it and feel the comfy soft fabric (jersey). But when i unravelled it, I realized my size small looked like a huge sack especially for my small frame. I'm 5’6’’ and 115 pounds. I figured I needed to work with this. So I hiked up the bottom of the dress to the length shown in the photo and pulled the top of the dress downward to give it the slouchy appearance. Cool, right? But the problem is that even this did not work with this dress on me. The bottom slipped down below my hips when I dared to walk. I’d love to try this dress in an XS, but they don’t make it in an XS. I'm sure this dress will fit other women, but sadly it doesn’t fit me. Also the ivory is a nice color but it would be pretty if designed in other pastel colors
