A high-waisted mini skirt is the best choice if you want to face summer heat. Wear it with a tucked-in sleeveless top and high-heeled sandals, or for a more relaxed look, take a pair of flat sandals. Make sure the fabrics used are breezy and comfortable. If you are more boyish, a ruffled high-waisted skirt and a simple tank top will add some curves to your figure. If the silhouette allows you to, you can pick a tighter skirt. However, in order to balance the look, match it with a loose t-shirt.

High-waisted loose shorts, made from soft fabrics, are so versatile and can be worn in so many different combinations in order to create casual and more elegant outfits. Match them with a loose tucked-in shirt and a pair of platforms.
You can replace the shirt with something more effortless such as a basic t-shirt, and if it gets a little bit cold, you can take a denim jacket or a boyfriend blazer over the tee.
