Ah, yes, the blistering heat has arrived—and I bet you've already whipped out all of those summer dresses and halter tops from the back of your closet. But the warm weather also means air conditioners will be blasting at full force indoors. It may be nearing 100 degrees outside but my office is sure to feel like the tundra. And because of this, a good lightweight jacket is a must to keep the goosebumps at bay. These bad boys will also come in handy for movie theaters, plane rides, or those chilly summer nights when you're out after the sun goes down.

As far as styles, denim, moto, and bomber jackets will keep you at just the right temperature whether you're inside or out. Alternatively, switch up your typical hoodie or sweatshirt situation with a trendy blazer! No matter your situation, you're gonna love our fave items...
