Do I really need a reason to shop?

I recently started a new job...YAY! In my previous job, my work dress code consisted of jeans, jeans, and more jeans. I would wake up and figure out what jeans I wanted to wear and then decide if I wanted to dress them up or down. The process was pretty simple. Now, I work in a business casual environment and after just two days at my new job I'm struggling to figure out what to wear Monday. I love a good reason to go shopping (I'm sure my husband isn't a fan of that philosophy), but I feel like that's the easy way out. So this weekend I'm asking for your advice on how I can spice up some items I already have in my wardrobe. I already have some ideas but I'd love to hear all suggests! Thanks and have a great weekend everyone :)
