One non-heat-exhaustion-causing way to wear those over-the-knee shoes? Top them with a short, sleeveless dress. Your look will stand out because it’s stylish, while still showing enough skin to keep cool.
That long sheer chiffon shirt that’s kind of hard to wear will certainly come in handy when the weather starts to turn… Dig it out of the back of your closet to cover up and keep from getting chilly off while dressing up even the most casual of summer outfits.
A basic top + skinny jeans are a totally warm-weather appropriate combination, but a draped structural blazer paired with a chic but comfy slip-on sneaker or top-sider gives the easy look an autumnal (as in your shoulders and toes are completely covered) twist.
In a few short months, yummy sweaters and structured skirts will serve as cozy winter pieces, but for now, pair a sheer, open weave sweater (breathable!) with a miniskirt for a fashionable grown-up-schoolgirl look.
I hope this guide helps you while the sun is still shining!
