Catie.
I had Catie get in the tub and fired a Flashpoint/Godox AD600 Pro from the hallway about 8 feet away from the bottom of the image using the closed frosted glass door of the bathroom as a modifier. From there, I precariously climbed onto the rim of the tub, dialed in the shot at 29mm, 1/200 sec, f/4.0, held the camera way out over Catie and clicked the shutter. A couple months later I realized it would have been much easier just to mount the camera on the end of a c-stand, level it out properly, and fire it with a remote trigger, but in the heat of the moment you just play around with what's in front of your face.
Lots of color editing in Photoshop, mostly with HSL layers. The dress is actually green.
