With nationwide heat waves causing record-breaking temperatures, this summer hasn’t necessarily been kind to us. Outside of taking the proper precautions to stay cool, like swapping your tried-and-true sheets for a set of cooling ones or running multiple fans to keep air flowing, choosing the right clothes is an essential part of staying comfortable throughout the season.

Along with must-haves like shorts and airy linen pieces, casual summer dresses are lifesavers during this time of year. They often come in a variety of styles and lengths, but the most popular tend to be T-shirt, tank, swing, and maxi dresses. If you’re trying to beat the summer heat without sacrificing style or comfort, we found a selection of relaxed, versatile, and chic options at Amazon for under $30.

With adjustable spaghetti straps, decorative buttons, and—wait for it—two side pockets, the dress is versatile enough to dress up for a summer party or dress down for running errands. “It is light but not see-through,” one shopper shared, adding, “It looks cute with a wedge heeled shoe or a sandal, as well as a sneaker shoe.” Did we mention it comes in 43 different colors and styles?

Elescat Sleeveless Tank Sundress

You can’t beat a tank sundress once the warm weather rolls around, and this piece from Elescat is a great option for casual outings, parties, and more. For starters, you’re guaranteed to stay cool and comfortable in the dress thanks to its breezy blend of cotton and polyester. “I love the feel of the fabric on my skin and the prints are gorgeous,” one reviewer wrote. “I liked it so much, I bought more in different prints.”. The dress design features a scooped neckline, swing hem, and side pockets, which add a touch of flair that instantly elevates your look. In addition to those impressive features, the dress is available in over 40 colors and comes in sizes S to 3XL. 

Amazon Essentials Surplice Dress

Amazon Essentials has an extensive line of clothes for all occasions, and this dress is no exception. With a V-neck overlap neckline, elastic empire waist, and dolman-style short sleeves, the dress can easily be styled with wedges or heels for more formal occasions, or worn with sandals or sneakers at backyard barbecues. “Whether I’m dressing it up with accessories for a night out or keeping it casual for a day at the park, this dress always looks amazing,” one five-star customer shared. The fit-to-flare style flatters the chest and waist, but conceals problem areas thanks to its flowy skirt. Plus, the rayon and elastane blend provides plenty of airflow to help keep the summer heat at bay.
