It's time to let go of all your bad head-to-toe denim memories from high school. In 2015, denim dresses are the trend for transitioning from summer to fall.

You see, even though fall fashion is on our minds, it's nowhere near chilly enough to whip out our sweaters and scarves -- that's why denim dresses are the perfect trend to wear during the seasonal transition. They're light enough for balmy days yet warmer than their sundress cousins. We're taking our inspiration from Alexa Chung, Elle Fanning and other icons and put together this collection of our favorite denim dresses right now.
