I’m a very strong believer that casual dresses make the perfect summer uniform. They’re easy to throw on (only one piece vs. multiple), they’re comfortable, and they keep you cool on those extra hot days. Not to mention that a lot of the time, they’re super affordable too. 

My closet is overflowing with T-shirt dresses, midi dresses, and breezy sundresses, but sometimes, I find myself struggling to decide how to style them. I usually want to keep it pretty casual, but it’s easy to feel overdressed when you’re wearing a dress.

Because of that, I decided to make it my mission to find the cutest casual dresses on the internet—broken down by T-shirt dresses, midi tank dresses, mini dresses, flowy dresses, and knit dresses—so that we could figure out how to style them together.

Check out the cutest casual dresses to add to your cart right now, plus how to style them:


1. A T-shirt dress

dress / sandals / belt bag / sunglasses / claw clip

T-shirt dresses deserve a spot in all of our closets purely because of how versatile they are. They are so easy to throw on and go, no matter what you might be up to that day. While you could always go for the obvious and throw on some white sneakers and your favorite tote bag, an athlesiure look is a fun way to switch things up.

2. A midi tank dress

dress / sandals / tote / sunglasses / necklace

dress / sandals / tote / sunglasses / hoops

I like to think of a midi tank dress as the cool older sister of a classic t-shirt dress. It’s a little bit more trendy, but still can be very casual and comfortable to wear. These are perfect for a summer day of activities and errands, so keep it comfortable with a pair of slip-on sandals and your go-to tote bag.

3. A mini dress

dress / sneakers / bag / hoops / clip

While it may seem bold to put on a mini dress, I promise that there are options out there that will still make you look and feel confident and comfortable. Since these types of dresses can easily lean on the dressier side, opt for sneakers and classic accessories to keep it casual.

4. A flowy dress

Is there anything better than a loose flowy dress during the unbearably hot summer months? I think not. Paired with strappy sandals and fun hair accessories, a flowy dress will make you feel like you’re just hanging out on an island—which is exactly the vibe I’m striving for this summer.

While knit dresses might be the newest addition to our casual summer dress repertoire, they definitely deserve a spot in our closets. A knit dress is the perfect way to achieve that effortless cool girl look, while still being comfortable enough for a hot summer day. Pair one with sneakers and ’90s-inspired accessories for a trendier look, or opt for classic with crossband sandals and gold sunnies.
