How was this soft lighting done?

Im having a tough time getting the exact lighting setup by looking at the catchlight because it seems to be above the subject. I cant tell if its some weird window or a large octa or softbox or what, does anyone have an idea?

Looks like a rectangle softbox eye level camera left .

If you keep trying to find out "exactly" what someone else does or uses, you'll lose your mind. All you really need to do is come close..... I would say that this modifier is 60" (5 feet) or larger. Most likely an umbrella with a front diffuser over it (I think it's call a Soft Lighter). Also, could possibly be a Octadome/Softbox.
