I don't often wear button down shirts, due to the fit and/or fabric, but I love this one. I bought a L and an XL. I could have gotten away with the L. It was not tight on the shoulders or the hips, but, while it didn't completely gap at the bust, I felt like it may have with various movements. I felt a lot more comfortable in the XL, which was a better fit for me. I'm usually a L, but I feel like the bust area on this shirt is the snuggest, and I don't like the possibility of my shirts gapping.
For reference, I am 5'5\", 170, 38-36-44.
If you are on the fence, buy it!! It's gorgeous, and it makes a statement!! :)

Exactly what I was looking for. Light fabric so I use a cami underneath. But it matches so many of my clothes. Great purchase.

Purchased for a business trip to wear in office and this was definitely my favorite outfit. I got so many compliments on this shirt! It’s lightweight, comfortable, and easy to dress up or down.

I usually wear a large but got the X-large, especially because I have a bigger chest; I was worried the fabric was going to gap between buttons. I have no gap with the size up. My shirt is soft and drapes well on the body.

I absolutely love this top. It's soft, good quality, beautiful art piece, and you can wear it casual or dressed up. I would recommend dry cleaning or delecate washing with hanging the top to air dry. I am usually small in tops, but got medium to have a little more oversized look.
