There are all kinds of control. One is choosing what your sub wears, or doesn't wear. Men may assume you will pick out something sexy or something fetishy. Why not pick out something colourful, stylish, something like a really nice suit and tie?
Men don't tend to wear pretty colours. How about this Spring green tie? The dark shirt sets it off. It's pretty and yet not girly looking. I really like this look. Why not dress your little man up, pick his look for the day in order to please yourself. It's not an abuse of power... he says he wants to please you after all. This just isn't something he was expecting.
Keep him on his toes... pick out new shoes too. What about those old fashioned lace up leather shoes with wing tips? Maybe a shirt with bright polka dots? Wouldn't he look nice if he were dressed in a few bright, happy, Spring colours?
