Hi Emily,
This top is a button down top, made of standard t-shirt fabric which can be slightly sheer. It has also absolutely no stretch at all. These kind of tops are not designed for women with large busts because, like you said, the buttons will look stretched out.
This particular top is just a standard button down shirt with a peplum detail which makes it different than all other shirts. It looks exactly as photographed. But it will not work on everyone, because it isn't a piece that stretches to your form. It is rather structured.
In the future, it would be best to contact our team if you need further details on any of our pieces.
Thank you,
