This first look centers around pink binary leggings and comfortable sneakers, which I liked from the original outfit. Throw a trendy sweater over a black tunic-dress and I don't see any reason a computer engineer wouldn't wear this. And a laptop bag - pink yes! - but I am sooo surprised that she didn't have a laptop bag!
This one looks a little bit more grown up to me and takes more from the original look. The boyfriend blazer, though, would have the binary code on the folded sleeves - another little detail I liked from the original look. The flats are also a great alternative to the sneakers.
