You can use a few adjustment layers and masking.
Create a selection for the affected area. You might want to do this with pen tool for precise selection. The left side won't matter much because we'll mask it soften and blend with left portion of image. Right side edges of the jacket/clothes are the boundaries, so selection needs to be better.
I used quick selection tool for demonstration, you can use pen tool for more control. You can use same selection for all the adjustments and modify the masks individually. That's what I'll do. Also I've highlighted (yellow arrows) which portions will need soft brush in mask area adjustments:
Selective Color and reduce the values of Magenta, Red a bit:
Hue and Saturation layer to reduce saturation of Magenta, Red
and blue a bit:
Now, you might have lost some blue color details. So add a
Color Balance layer to 'bring' back some blue and green maybe.
Another layer to make it a bit warm:
Now the right side look a bit brighter (ignore if that's 'natural'
or you want it as it is), so add a
Levels layer and make it a bit
less bright and add a soft mask so it affects only right portion.
And make other tweaks/fixes by cross checking previous layers:
Note: All those adjustment layers, especially color related are not necessary. Feel free to ignore which you don't feel like needed.
The idea is to tweak things and mask and try to see what works best. You'll need to mask with soft brush at some points. Reduce or emphasize the adjustment layers using mask wherever necessary. Try different sizes of brushes and different opacity values. Try adjusting opacities of layers themselves.
About the color changing part, you can use Gradient Map. Your question is a bit unclear to me, but if you want to change colors of the clothes, you need to decide 3 or 4 main colors (some darker, some brighter) of the look you want to create and use them in
Gradient Map adjustment layer (use a selection where you want to apply). Something like this:
Or if you want to change entire image look and feel to a single color, you can use a solid color (or paint in a new layer manually with a solid brush, only the areas which you need) and try changing its Blend Mode to different modes like Multiply/Screen. See what works best for you. A few examples:
Photo Filter adjustment layer too in case you want to try.
