I am sure a lot of people enjoyed the "business attire" uniform included in the 2K Image Patch upload by DomoeYuse; I know I did.
This mod runs with that thought and includes a similar uniform to the one just mentioned for each MLB team with an assortment of colors.
All of the 30 teams have one uniform in this pack which replaces the regular Home.
Obviously, if you'd like to add one or some of these and keep the home uniforms, these can be swapped to other slots.
You will get much more out of these uniforms if you use the included Color List and Ty's Editor, however, no editor is required for these to work.
If you are not using a Mod Enabler, be sure to back up your original files, and then place these in the main MLB 2K12 Program folder.
Thanks to DomoeYuse for the inspiration and to KC for producing such good conventional uniforms which served as great templates.
I have attached some screen shots for you to take a look at. Enjoy!
