Today I did a photoshoot of a twins. I was excited about the photos until I looked at several pictures of one girl wearing a red/pink shirt on my computer screen. The face was not over exposed but the red/pink shirt was! I lowered the exposure by one and half stops in LR and it still looks bad, so I just keep the original exposure I shoot. I like the lighting on her face and her expression so I do not want to throw the picture away.
What does it look it? It is bad? How to fix it?

Yes it looks bad or at least it would look better without the error. Here's what's wrong: The red channel is nuked:

The green and blue channels are fine and the exposure overall is fine. Looking at your EXIF data it appears that you processed a camera JPEG through LR which leads me to assume this error was introduced by the camera JPEG processor.
How to fix? Don't do it in the first place which brings me to the question do you have an NEF file? This error would be easy to avoid when processing the raw NEF file. You wouldn't create the error in the first place and you'd have nothing to fix.
The damage in the case of this JPEG is done and so you can't "fix" it you can repair it. It's a subtle distinction but an important one. If you break a vase and glue it back together you're going to see the break lines and the glue job.
If a repair is your only option then what you need to do in this case is adjust the red channel separate from the other two. Since the other two channels still have detail in the areas where the red channel is blown the repair will work pretty well.
But first: Do you have an NEF file?
