Hi everyone! I have been looking around this site for a few days now, and am so excited that I found you all! I have been wanting to re-do my wardrobe for a while now, but I always felt so overwhelmed. Now I'm thinking I can do it, one step at a time.

So here's my question...I'm 23, and work at a 'business casual' office. We CAN wear jeans, but they'd rather us not. Since I just started about a year ago, I've been wearing jeans. Now I'm ready to grow up, and start dressing better. So I'm wondering if I need to be shopping in the Junior's department, or Womans or Misses? And what's the difference between woman's and misses?
Also, I am young, and at an entry-ish level job at my employment. I don't have much money at all, but really want to get some long-lasting items. I can afford maybe $50/month or so. What stores should I shop at? Up until now I've been shopping at Forever 21 when I'm feeling brave, also Charlotte Russe. Otherwise I go for Sears and JC Penney, which I know aren't very high end. I'm still developing my style and learning how to put colors together, so I really need some help!

Some stats: 24 years old, 5'2", and 125lb (working to lose a few) and I think I'm a pretty pear.

Sorry this turned out so long...I could really use some help, though!
