I don't have a serious bag. Only because honestly, I take all of my husbands hand-me-downs and he's a messenger bag carrying fool. So, not only are my bags all dingy and used but they are usually very masculine.
But for some reason my husband has refused to have a serious bag, even now in a very serious position, he still carrys the "urban" messenger bags with stencils on them.
However, now that I'm in my "Budget Fashionista" project... I have been eyeing some serious bags - there's been a few at Target that I really like!
