This dress is to die for. The strap on the back is adjustable and so are the halter neck ties so it’s adjustable. I got a size small because I didn’t want it to be too tight to the point where I was uncomfortable, so if you want it to feel like 2nd skin you can size down, but if not just stick to your normal size. It also makes the girls look good so this dress is also itty bitty committee approved. I’m 5’7 and it’s long enough to drag a little so I also love that
