Beautiful dress which exceeded expectations. I bought a size smaller than I needed with the intention of slimming into it for summer, but it already fits perfectly, so I would say if you are between sizes then size down. I also have a large chest (f or g cup) and it doesn’t squash my boobs down like I find with some higher neck dresses.
Please bring this style out in other designs and colours, I could see it being a staple in my wardrobe with the option of dressing up or down.
