I like the fit of this top, it is very slim. I don't think it would be good for someone with large breasts. I ordered a small and am a 34C 36 B. It is a bit more snug than I prefer in the bust.
I love Landau because their sizing is always so comfortable. This medium felt like I was squeezing myself into an extra small!
This is a great top, and I love the neckline, but for someone like me who is petite, the top was a bit long. I probably should have purchased a petite. But having said that, the top itself is really nice, and there are so many great colors to choose from. It is comfy and looks nice on.
