Summer may be the sweltering time of the year, but that doesn't mean you can't look -- and stay -- fashionably cool. Take a style inspiration from Selena Gomez for an effortless, fresh summer look.

Style inspiration: A cool headband

Wearing your hair up lets you keep your cool as the mercury rises. Accessories like a retro polka-dot headband scarf instantly dresses up a casual ponytail or bun for a cute, retro-esque look. If you don't have a headband, you can easily construct one from a scarf -- fold it in half into a triangle then roll up and tie around the head, making a tight knot at your nape.

Style inspiration: Cool oversized earrings

Hair worn up lets you flaunt those statement earrings, which are very much on trend this season. A pair of large hoop earrings like Gomez's are a summertime classic.

Style inspiration: Cool shades

Much more than a fashion accessory, sunglasses also protect your eyes from the sun's harmful UV rays. A large pair of shades like Gomez's is ultra-trendy, and also shields your peepers from most angles. When you're shopping for one, look for the label that says 99% or 100% UV protection.

Style inspiration: A cool top and denim cut-offs

Loose, airy clothes are a good bet in the hotter months and lets your skin breathes. Go for lightweight cotton and linen and stay away from tight, synthetics like polyester. Top it off with a pair of denim cut-off shorts that channels laid-back cool. (You can snip your own DIY cut-offs from an old pair of jeans.)
