Open-minded husband....was he so?

It was when one of  my friends told me that her husband became a self proclaimed generous gentleman by permitting his wife to wear clothes of her choice.... Her husband  told her that he is a very open minded as he allows her to wear what ever she wants....He is ok with her choice of clothes...
  .. Though my friend was pissed off after hearing him but she chose not to argue...

Later I thought why  was he giving approval when she was not seeking for....
Who has made him superior enough to permit his wife to decide as to what to wear n what not.....
 Her husband has himself given him authority to decide his wife's attire......n he thinks he is generous n open minded in doing so.......was he right.....was he open minded...????or such men called something else....
