I haven't participated in the back-to-school frenzy for about four years now, but let me tell you I miss that feeling. You know what I'm talking about. The hunt for the perfect book bag, the

smell of fresh school supplies when you walk into stores, texting your friends your class schedule and praying you got something together… Honestly, I envy those who are headed back to campus this year. 

Even though I'm not, I'm going to act like it because H&M just came out with the cutest back-to-campus collection, and this 25-year-old is here for it. Tennis skirts, pink sweater-vests, and oversize cardigans are filling me up with nostalgia. Headed back to school or just venturing back into the real world? Keep scrolling for 15 H&M pieces that are perfect for any fall activity—whether you're sitting in math class or running to your local coffee shop.
