Yes, we're still in the midst of summer's hottest months when the most comfortable thing to wear outside is a bikini, but it's never too early to start thinking about next season's wardrobe. Chillier weather is right around the corner (eek!), which means lightweight fall jackets will be coming into sartorial play in no time. Rad outerwear is what makes a cold weather outfit stand out, so you'll want to make sure your arsenal of options is fully stocked with a diverse range of styles.
The two must-have jackets, at least in my opinion, are a leather motorcycle jacket and some kind of denim jacket. One or the other will always go with anything and, if you buy a fleece-lined denim jacket, they'll both keep you pretty warm during the fall. Outside from those, a sharp blazer, fuzzy teddy jacket, classic trench coat, and sporty track jacket are all ace styles to add into your wardrobe too. Below, I rounded up 25 of the best lightweight outerwear options currently on the market for under $100, because staying warm and looking cute while doing it shouldn't cost you an arm and a leg. Pick out a few of your favorites now and be prepared for when that first chilly day hits.
