Sir's dress code for me does not include pants, mostly. He currently makes exceptions for my outside job (though I'm trying to work in more skirts and dresses there also), and situations like this, job interviews where I have suits. I suppose I should invest in skirt suits for the future, but suits are expensive. So for the time being, I'll wear what I have.
If I get the job I'm hoping for, I'll have no real excuse not to wear a skirt or a dress everyday, much to Sir's delight I'm sure!
