A shirt dress, one of the most comfortable items in my closet. I have a few in my closet in different styles. They come in handy on so many occasions. I mostly find myself wearing them to work on a Friday.
I have this rule I follow regarding dress down Fridays. Do it with class. I like to wear more casual looks on Friday, but you will never see me wearing jeans. On those days when I just need something to work. I denim shirt dress will always do the trick.
