The perfect throw-on athletic dress (with built-in shorts!)
Size: Small, Color: Navy Blue
I’ve been loving this athletic dress—it’s one of those pieces that’s both functional and cute, which is hard to find. The fabric is lightweight, breathable, and slightly stretchy, so it’s comfortable whether you’re running errands, going for a walk, or just chasing kids around all day.
The built-in shorts are a huge plus. They stay in place well and make it feel more secure than a regular dress, especially on busy days. I also appreciate the pockets—they’re actually usable and don’t feel bulky.
The fit is relaxed and flowy, which I personally like because it’s easy and flattering without clinging. The straps are adjustable, so you can customize the fit a bit depending on your height or preference.
I’d say it runs true to size for a looser fit. If you want it more fitted, you could size down, but I like the casual, sporty look as is.
Overall, this is a great everyday summer staple—super easy to style with sneakers or sandals, and perfect for travel or on-the-go days. I’ll definitely be getting more colors!

Perfect for summer days.
Size: Medium, Color: Deep Gray, Size: Medium, Color: Deep Gray
I absolutely love this little athletic summer dress. I typically wear a size ten and ordered this in a medium and it's a perfect fit. I have the straps short so way it doesn't look baggy. It is super soft and comfortable. It is breathable and a perfect cut and length for me so so I plan on wearing it all during hot summer days. This is very versatile and easy to style by layering different things underneath it. I have a gray and leopard sports bra that is a really close shade of gray so it almost looks like it's one piece. I plan to order the teal as I have a swimsuit top that will match that color spot on. It seems like it is good quality and should hold up well to normal usage. I like that it has really big pockets , but I likely will not use them often lol. I just like the fact that if I need to have pockets they are there.

Size down! But overall comfortable and cute and good quality
Size: Small, Color: Light Yellow
Overall it’s cute and comfortable, but my advice is to SIZE DOWN!!! I wish I would have, but I’ve already washed it so it’s too late. The straps are adjustable, but even so, I’ve had to tighten them as far as they’ll go. For reference, I am 5’1” and 125#, rectangle shaped/boxy body with a very small chest and I got a Small. The top gapes open on me and the dress is longer than I prefer for this style. Material/fabric is nice and good quality and it’s a perfect one-piece easy outfit for warm days. I like the yellow color too. It is tricky to find the right bra to wear with it, though. Got lots of compliments on it the first time I wore it.

Cute, Comfy & Flowy—Great for Plus Size!
Size: XX-Large, Color: Black
I really like this dress!
It’s super comfortable and lightweight, and the material feels soft without being too thin. It has a nice flow to it, so it doesn’t cling to your body, which I really appreciate.
For reference, I’m 5’4” with a 46” bust, and the dress fits well overall. The length is great, and I love that it has a relaxed fit—it’s easy to throw on and still look put together.
The pockets are also a nice bonus and actually usable.
The only thing to note is the top area can be a little more open on the sides, so I personally prefer wearing a sports bra or something cute underneath. It actually works really well styled that way and gives that “layered” look.
Overall, it’s a really easy, comfortable dress that you can dress up or down. I’ll definitely be wearing this a lot!

Great dress for running around town
Size: Large, Color: Coffee
I love this dress. I ordered this dress fist in a medium, then a large. I probably would have been fine in the large, but I just wanted a little more room and I wanted it to come to my knees so I ordered the XL and I love it. The material is a cotton knit type material similar to a t-shirt with a little stretch to it. I am 5'2", #170 and the XL gave me the fit I was looking for, being loose and comfortable. There is a second layer under the dress that has shorts and a tank top built in. Unfortunately, you must take the entire thing off to use the restroom but I am considering adding snaps to the crotch so that it is easier and I won't have to completely undress to use the restroom. The olive/army green is beautiful and I am planning to order the plum color dress as another addition to my summer wardrobe.
