If you've become so obsessed with your new summer sundress that you can't imagine putting it in storage after Labor Day, relax! Here's how to style your favorite summer pieces for next season—by mixing in a few sexy fall trends.

1. SHORTS

Layering a fall trend—like a cape or a fur vest—with your favorite summer shorts will take them from warm weather must-have to fall wardrobe staple. Or turn your hotpants into a hot suit wearing them with a sexy, sheer blouse and a matching jacket.

2. JEANS

Wide-leg jeans have been huge all summer—fortunately, they transition easily into fall. Pair them with a plaid top for even more '70s flair. And your favorite summer skinnies will look awesome with trendy metallics. Gray denim works especially well with shades of gold and bronze.

3. MAXI-DRESSES

Do you have a long dress you're obsessed with? Good news: You can still wear it next season! Layer it under a thin sweater for a stylish look. Feminine floral dresses look great with edgy, rockerish leather jackets—it creates the perfect soft-hard balance. Or switch to pumps: when you swap out strappy sandals for closed-toe heels, your sundress instantly becomes less summery.

4. LIGHT BAGS

Don't retire your cream-hued bag just because the leaves are changing. Carry it with darker, solid separates for a fall-appropriate look.
