Help! My Internship is Giving Me a Shopping Problem!

It's true.  My upcoming internship is giving me a shopping problem.  These end of season clearances and sales are draining my budget.  It's been years since I had a need to go shopping for office appropriate clothing but I knew that I would need to stock up on office attire before my internship started so I set aside all of my graduation money to spend on a new "grown up" wardrobe.  Here's the problem...I'm having too much fun buying all kinds of cute work clothes!!  And now that I have cute work clothes, I need matching shoes which is strange because I have never been much of a shoe girl.  Usually, I could care less what my shoes look like as long as I have a cute purse and other accessories. I don't know what's come over me, but I suddenly need a pair of dress shoes in every color.  I have purchased five pairs in the last three days.  Luckily I'm quite the bargain hunter so I've only spent $60 on all five pairs but this internship needs to get started so that I can quite spending money!
