NEW YORK ( TheStreet) -- Have your bought your child a backpack with pop sensations One Direction on it, or a spiral notebook plastered with the family on A&E's reality television series "Duck Dynasty?" Apparently these are two of the season's hottest trends in school supplies. Less than a month from now, most schools and colleges around the country will be back in session, with students sporting the latest fall clothing trends, hot electronics, gizmos and gadgets, all to kick off a fresh season of learning. For retailers, "back-to-school" is one of the biggest shopping seasons of the year, second to the Christmas holiday season. Of course the most popular categories to shop for are apparel and electronics, but plenty more retailers will see a lift from school supplies and sports gear to dormitory furnishings for older students. Besides One Direction and Duck Dynasty, this year kids will be sporting apparel and supplies doused in neon, licensed NCAA decor and animated character favorites from movies like Monsters University, according to a Wal-Mart survey. Consumers are in full shopping mode right now for their school gear, even though early reports say that, sales are slower than usual. Total back-to-school and back-to-college spending combined will reach $72.5 billion, the National Retail Federation estimates. Families with school-age children are expected to spend an average of $634.78 to prepare for school, 8% less than they spent in 2012. Those with college-age students will spend approximately $836.83 on gear, also 8% less than last year, NRF says.
