Promising review: "GORGEOUS. Will wear this for my niece's rehearsal dinner in the Bahamas...I like the weight of the fabric versus the cheap, flimsy see-through fabric we see a lot of. Also, the skirt portion is cut on a bias, which is very [nice]... If you’re petite, order a petite. It’s asymmetrical, so one side is like a maxi and the other to the knee or midi.

It's a real confidence booster!" —Gr8ful Nurse

Promising review: "I was worried about ordering this dress because some of the reviews stated that the sizing is weird. I'm 5'4" and around 112 lbs, so I ordered an XS, and it's PERFECT! I wore it to my brother's wedding and got so many compliments. The straps being adjustable helped to make it a perfect fit. This is my new go-to dress for weddings and other events.

Promising review: "I ordered this dress for my cousin's upcoming wedding, and I am over-the-moon happy with it! The fit is true to size, comfortable, ...and it fits like a glove!

Some reviewers even wear the dress backward with the tie strap in front for some cutout action, and it looks just as gorge. You'll be obsessed with the versatility!
Promising reviews: "Very cute dress! I wore it to a country-themed wedding...The fabric in the middle is very stretchy and comfortable, but hugs in a very [nice] way. I saw other reviews that said you could wear it backwards as well and I can confirm that! I also like that I can wear a normal bra with it, the tie can be wrapped in a way that hides the back of your bra and your straps stay under the sleeves as well. Definitely would order again!" —Kelsey
"Don't walk, RUN!!! I was skeptical about this dress. I’ve never bought clothes from Amazon, but I just liked this dress so much I had to try it, and when I tell you it’s perfect, it. Is. Perfect!! I bought this as a dress to wear to my boyfriend’s brother’s wedding (which is tropical cocktail attire). As a bigger girl, size 16/18 I was nervous as to whether the stretch was actually stretchy and would the sheer sleeves actually fit my arms, both of which were easily assured when I tried the dress on. Let’s start with the sleeves, very sheer, just a single thin layer, but very roomy and loose, perfect for an outdoor summer event... The waistline [has] a great amount of stretch to accommodate a larger body or bust. The skirt flairs out perfectly, and the length is perfect, too." —Barbara Lambert
Get it from Amazon for $37.99 (available in sizes XS–XXL and in 19 colors).

26. A lace cocktail dress with a high neck (making it perfect for fancy black-tie events) and short sleeves (which makes it a daytime go-to)!
Promising review: "This dress was PERFECT for my friend's wedding. I saw a similar dress on another site at almost double the price, and I decided to take a chance on this. I am SO glad I did! It fit perfectly — it wasn't too tight or uncomfortable. I love that it's classy but still fitted and has the slit in the back for flair. I may even buy it in another color!" —Lauren Pearman
Get it from Amazon for $39.99+ (available in sizes 4–12 and in two colors).
27. A corset dress with a high slit that'll have you strutting like it's New York Fashion Week! The satin material and long flowy hem make it perfect for a spring wedding.

Promising review: "This is a very beautiful, fashion-forward dress. It looks just like the picture. I wore it to a wedding and received many compliments. Please note, the dress is not a stretchy material. Although I ordered a size up, I would suggest ordering one or two sizes up if you would like the dress to fit loose or fall closer to your knees because it’s very short." —Quinna LaMark-Smith
Get it from Amazon for $39.99 (available in sizes XS–XL and in four colors).
30. A unique one-shoulder smock dress because its basically just a stretchy, comfy, and cute package wrapped into one. An easy piece to dress up or down, because it'll always look great either way!

And I simply cannot get over how great those dangly crystal earrings look with this dress — here is a similar pair if you want to recreate the look!
32. A midi-length satin dress with a cowl neck because it may just be the easiest stylish outfit there is. A satin dress with sneakers during the day is edgy, but a satin dress at night? Epic!

36. A pleated swing dress featuring chiffon material that's both chic and comfortable. Plus, the huge color selection will ensure you find the perfect color. (P.S. It comes with an optional belt, too!)
Promising review: "Possibly the world's most perfect dress. So many ways to wear this beautiful dress! It’s so versatile, you get more than you pay for. It comes with a detached belt of the same fabric so you can make it fitted on the waist, but I love the dress without it. So elegant. The fabric can be dressed up for evening with a glam heel and the right jewelry, or dressed casually for daytime with a leather belt and denim jacket. You can really do anything with it!" —Lacey
Get it from Amazon for $35.99 (available in sizes XS–XXL and in 29 colors).

Promising review: "This dress is so gorgeous, well-made, and very comfortable! I purchased it to wear to a Military Ball. There is nothing about this dress that's ill-fitting, rough/scratchy, or uncomfortable. The outer layer is very light and flowy. The inner layer is still lightweight, but more silky. The cups are also lined in this same silky material. I don't know that I'd be able to wear a bra with it, as it does show a bit of side boob. But, the cups feel somewhat supportive...Great dress — BUY IT! It would be awesome for bridesmaids or for [someone] to wear as a wedding guest, prom, bridal shower, etc." —ALC123
Get it from Amazon for $81+ (available in sizes 0–30 and in 26 colors).

Get it from Amazon for $44.99 (available in sizes XS–XXL and in 35 styles).
40. A flowy evening gown with a chiffon shoulder train that'll make anyone feel like a goddess! The bust area has gorgeous ruched detailing, and bonus points! There's enough padding to forgo a bra.
Promising review: "I bought this dress and four others for the inaugural balls. This one fit like a dream! I had it hemmed but otherwise, it fit well and I had compliments all evening. The dress is so classy and elegant. I can't wait to get a different color and have it on hand for other events. Definitely a go-to option for black tie affairs! I got the size based on the bust and it fit great!" —Destiny Decker
Get it from Amazon for $89.99 (available in sizes 0–30 and in 28 colors).
41. A mini rosebud dress so dang adorable, it'll even have the bride doing a double take as they spot you while walking down the aisle. If spring were a dress, this would 100% be it.
