Shopping dressing room
 

Is there a mod that allows you to "try on" the item that you are planning on buying from the merchants or marketplace? If there is not, is it even possible to make one?

Click/highlight the item of interest. Hold down the CTL key and left or right mouse click it, depending how you have your mouse configured. If it can be viewed in the dressing room, that item will be displayed on your character. If its a house item for example, that will appear in the dressing room as well.

You would think that was easy to find, it would be nice to have it on a right click drop menu or something.
