Free People Adella Slip Dress
The Adella Slip Dress is one of Free People’s most popular styles because of its dainty silhouette. The asymmetrical hem, lace trim, and smocked design add to the fairy aesthetic designed for frolicking. “The dress is super comfy and cute dress with a nice spin factor for anyone that loves a nice twirly dress for dancing. I was worried it would be too short but I’m 5’8” and it fit perfectly,” writes a reviewer.

BTFBM Ruffle Cap Sleeve V-Neck Boho Maxi Dress
Lightweight and breezy, the ruffle maxi is a summer staple for its effortless styling capabilities. The chiffon fabric is soft on the skin and comfortable to wear on a scorching, humid day. “I ordered my true-to-size (M), and it fit perfectly. The fabric is not itchy, which is a huge plus! Personally, I like to wear the detachable belt to accentuate my waist,” explains a reviewer. “The length hit me about mid-calf. I have worn it multiple times, and it washes well if you wash it cold and line dry. I also used a steamer on it in a gentle setting, and it held up great.”

Amazon Essentials Women’s Sleeveless Woven Shirt Dress
Here’s a breezy shirt dress perfect for a picnic or BBQ. It’s especially great for petites given its shorter hem: “I love this dress. It’s pretty TTS. I’m 5’3” and a normal medium. This fits great. It falls just above my knee for a perfect length! I love the pockets too,” writes a reviewer.

The waistband has a good amount of stretch, which is very comfortable,” shares a reviewer. “I wore it as a wedding guest, and it was perfect. I’m glad I sized down; the L was perfect. The dress is pretty well built; the snap closure is a good spot on the chest, the lining is soft, and the stitching is secure.”

HBEYYTO Short Sleeve Flowy Mini Dress
If you’re into a classic babydoll mini dress, the kind that you can simply throw on like an oversized T-shirt, allow this one to be your latest closet reach. “I cannot emphasize enough how lightweight and breathable this dress is! As a plus-sized woman, it can be hard to find dresses flattering to a larger belly area (especially shorter dresses that don’t show too much), but this dress is perfect,” says a reviewer. “On colder days, I add leggings under it, but I am completely comfortable with the length and fit to wear without leggings and not feel exposed to the whole world.”

If length is what you’re going for, this maxi with pockets shows just a hint of ankle. “I bought this dress for a trip to Mexico, and loved wearing it. It was comfortable and breezy in the hot/humid weather,” writes a reviewer. “The fabric is flowy and didn’t stick to my pear-shaped curves — it skimmed them and was very flattering.”

DKNY Faux Wrap Dress
Dig a little in the Amazon racks and tried-and-true brands like DKNY will turn up. This flowy number is a bit more put-together, ideal for a summer soiree. “This dress is gorgeous and perfect for wedding season! It’s very comfortable and flattering. Plus, if you have a smaller chest, you may need to use fabric tape to keep the top part from falling open when you sit down. I did that and it worked perfectly!” advises a reviewer.

Naggoo Ruffle Short Sleeve Mini Floral Dress
How darling is this summer dress! The wrap detail, the crossover top, the ruffle hem, the floral print…this is a frock begging to be seen. “This dress is absolutely fantastic. The fabric is comfortable. It’s lightweight with some texture to it. Also, it doesn’t have a cheap feeling at all. I am a size 8 generally and 5’3, about 150lbs right now. I have a 34D chest. I ordered a medium and it fits like a dream,” writes one enthusiastic reviewer.

The Drop Ana Silky V-Neck Midi Slip Dress
The R29 Shopping team’s own Karina Hoshikawa reviewed this unassuming but stunning slip dress a few years ago — and it still remains one of Amazon Fashion’s best-kept secrets. Hoshikawa writes, “The color is on point. The price is right. The shipping was free and fast. It’s comfortable. It’s cute. It can be dressed up or down with minimal styling effort required. But, perhaps best of all, the length was actually a true midi — aka hitting right at the calf on my 5’2 frame.”

Calvin Klein Ribbed Scoop Neck Midi Dress
We love a classic spring dress. This knit midi comes from Calvin Klein, and it’s ribbed, slightly bodycon, and has buttons down the front, which means you could also essentially where it open, belted, and layered over another outfit.

Bsubseach Crochet Cover Up
On the topic of beach coverups, this high-neck crochet style actually happens to be an Amazon ‘trending’ fashion item with its recent spike in sales. It seems like shoppers are ready for seaside adventures, and this dress is a must-pack. “I bought this for a Caribbean cruise and added a floppy hat and cute sandals and I looked (and felt) like a celebrity,” writes a reviewer. “I’m not always super confident walking around in my bathing suit, but this has just the right amount of skin showing to leave you feeling sexy yet modest.”

Zesica One Shoulder Tiered Mini Dress

PYGFEMR Short Sleeve Babydoll Dress
It’s no secret that this babydoll dress has very little shape or silhouette to it, but that’s precisely the point. We think this would make for a great summer dress if you wanna throw it on and go for an easy weekend. “Since I’m bigger chested, it falls straight in front of me so I’d only wear it with a belt,” writes one viewer. “It’s perfect for warm weather and to accessorize. So cute!”

Halife Casual Spaghetti Strap Midi Dress with Pockets
With 4.1 out of 5 stars and over 9K reviews, this spring dress could be considered one of Amazon Fashion’s classic styles. “This dress is so cute and simple! There are so many ways to style it and it fits perfectly! I always worry about the straps and length as I am very short and dresses tend to be too long or the top part hangs low on the chest but not with this dress! Only thing I wish is that the material was a little thicker. It’s very thin but helps it be a little flowy,” writes a reviewer.

Luvamia Denim Short Dress
Did you really think you’d get through an entire dress roundup without seeing a denim style in the mix? What we love best about this mini is the rather fitted silhouette with the varsity-style neckline. “What I surprise!! I had low expectations but was completely wrong! I love everything about this dress! The size is perfect, the quality is excellent! Love!” explains a reviewer.

Bdcoco V-Neck Floral Lace Dress
Yes, we’re very aware that this boho maxi dress could also look like a wedding dress (we should mention, it does come in multiple colors!) — but we simply cannot resist a lacy moment for summer. “The cut and color of this dress are very flattering. I’m 5’5″ 140lbs and the Medium fit perfectly. You don’t have to wear a slip under it, as the skirt and bodice are fully lined and very soft. My new favorite dress!” says a reviewer.

KOJOOIN Sheer Mesh Dress
While the model has fashioned this sheer dress into a beach coverup, we think that this dress would be much better suited as a layered piece over, say, a slip dress or bodysuit. The embroidered flowers are also a fun way to lean into the blooming springtime sun.

Mitilly Loose Swing Casual Dress
While most of the dresses in this roundup boast a rather traditional construction, this fluttery mini dress has some unexpected details, like an asymmetrical drop empire waist, three-quarter sleeves, and the all-over ruffle hems. Unique? We’d sure say so.
“I don’t usually bother writing reviews, but for this dress I had to!! I needed something feminine and youthful and fresh looking AND something that would make me look SLIMMER! JACKPOT!!” writes one enthused wearer. “I’m curvy and this dress drapes – PERFECTLY. I can even get away with wearing this to church – no tights and high heels and still look APPROPRIATE. Ladies, it takes me FOREVER to find something to hide all flaws and highlight the areas I don’t mind showing off – and this dress does just that!!!”
