Usually your main girl is not very into the holidays. In fact she usually decides to skip them all together (besides lighting the Hanukkah candles of course). This year thanks to YMG's over-enthusiastic mother, making her house look like an aisle out of your neighborhood party store, she decided to get into the chrismukkahspirit.
Your Main Girl is going to make this very simple: Printed Denim is in, shorts and tights are like so Europe, & adding any tee to a dressy outfit makes you look like you're a fu*king rockstar.
