13 insanely comfy throw-on-and-go dresses that don't look frumpy, starting at $21

This cute, comfy maxi dress has it all: a flattering design, an alluring slit and handy pockets. Plus, its roomy fit won't cling to your body, allowing for some welcome airflow.

This wear-anywhere wardrobe workhorse makes for a perfect summer pairing with sandals and a sun hat. And we love this look with a knotted bottom, to keep it clear from waves during long walks on the beach. Prices vary by color and print — 19 options are available ... and all have pockets (we love pockets).

Ideal for throwing on over your bathing suit or wearing to Sunday brunch, this swishy number has a high front cut, spaghetti straps and a side slit for maximum airiness. 

As one shopper describes it, "flowy and soft, with room to hide the least favorite body areas without being a tent."

Designed for all-day comfort, the dress has an A-line silhouette that fits loosely over the body and hits just above the knees. The best part? It has pockets! Available in 35 colors and prints.

This is the definition of comfy, casual and chic, with a flattering sheath design and a tie waist that creates definition in the midsection. Wear it to work, wear it to the beach, wear it in the backyard — the world is your stylish oyster.

Looking for something a little more dressy, that'll still help you keep your cool? Ideal for everything from brunches to baby showers, this swingy style is a little bit boho, which will make you feel effortlessly stylish, even in a heat wave.

Loose and leisurely, you can't beat the breeziness of this beach cover-up. It's made with a light and gauzy polyester that makes you want to sashay from the hotel to the pool to the beach to lunch without stopping to change — you're not going to find a coverup that's more comfortable. 

For only $36, why not get one, two or even three for your warm-weather wardrobe? This tiered maxi dress is light, soft and flowy, with a nice amount of stretch and thickness to prevent undergarments from showing through. The high waistline creates a flattering silhouette for a variety of shapes, and the tiered design adds a little visual flair.

Another option with pockets! Statement sleeves are all the rage this summer, so we're particularly enamored with these fluttery cap sleeves, which are just right for keeping shoulders sheltered from the sun's rays. This dress is available in 27 different colors, including neutrals like Black, White and Khaki; pastels like Mint Green and Sky Blue; and bold brights like Peacock and Rose.

The waistline is well-positioned to hide any belly bulges, while the shirred top makes for a slimming silhouette. And reviewers praise the fabric for being non-clinging and very breathable. 

Prints, prints and more prints — 24 options in total, with an additional 10 solid choices in pastel and neutral hues. From bold geometrics to romantic florals, this splashy stunner hits on all the right notes for a stylish, sunny-season wardrobe update.
