We found two equally affordable options that are super similar to Kate's dress.
Check 'em out ...AFTER THE JUMP!!!
The Spring Breakers actress looks so smoky on one cover (above) and ethereal on the other (below) in a Calvin Klein Collection dress.

On dressing for movies and music:
"If I'm going to the MTV Movie Awards, I'm going to dress a certain way, but if I'm going to the MTV Music Awards, it can be a little more out there. I mean, I'm probably the only one that notices, but, there's two distinct Selenas."
On her daily style:
"I do not give a damn what I look like, I don't. I wish I could pay attention because Gwen Stefani, say, looks flawless."
On her red carpet appearance:
"Of course, when I'm on red carpets, I'm nervous, sweaty and weird.”
Oh Selena! You just get more loveable every day.
And we think she’s anything BUT nervous, sweaty and weird!
Ch-ch-check out the rest of her spread (below)!
