Best Amazon Casual Dress Deals 

Casual dresses are arguably one of the easiest one-and-done summer outfits. Not only will they take the guesswork out of piecing together an ensemble, but they’re also lightweight, stylish, and comfy. There are several options below, including shirt, tank, and puffed-sleeved dresses starting at $30.

Cupshe Tassel V-Neck Ruffle Maxi Dress

Cupshe is known for its extremely cute swimwear, but the brand also has tons of cute dresses. This lacy maxi dress is proof; it has a pretty embroidered design, tassel detailing, and a high-low hem, making it perfect for brunches, tropical vacations, and everything in between. Shop it in 14 colors while it’s marked down. 

Merokeety Tie-Waist T-Shirt Dress

Real Simple readers love this T-shirt dress so much that they bought it several times during last year’s Prime Day—and they’re not the only ones who approve of the dress. In fact, it has more than 19,800 five-star ratings from people who like the stretchy feel, relaxed fit, and flattering appearance. 

Tommy Hilfiger Puffed-Sleeve Smocked Midi Dress

This Tommy Hilfiger dress is giving off total Nancy Meyers vibes, and we’re not mad about it. The denim-like dress has puffed sleeves, a smocked bodice, and cinched waist design that’s extremely flattering. You’ll also love that the sleeves can pull down off the shoulder to give you basically two styles in one.  

Best Amazon Sundress Deals 

Brunches, picnics, and family gatherings are just a few places you can wear these fun sundresses. They’re a touch more elevated than classic tee dresses, but have all the comfort you’re looking for this summer. Amazon is slashing prices on several of them, including options with floral patterns, wrap styles, and ruffle details.  

Grecerelle Floral Faux Wrap Maxi Dress

This floral maxi dress is an Amazon shopper favorite, earning more than 13,000 five-star ratings to date. Made with a blend of airy rayon and stretchy spandex, the dress feels lightweight and breezy, which is ideal for outdoor events. You can get it in this gorgeous floral pattern as well as solid colors and even polka dots.   

Zesica Strapless Lace-Trim Beach Maxi Dress

If you’re looking for something to wear at the resort this summer, this dress just might be it. It has a strapless design and flowy A-line skirt that’ll allow breeze to filter through as you walk. The dress has a pretty lace stitch and a tropical feel that’s great for beach days, too. 

Grace Karin Casual V-Neck Midi Dress with Pockets

You may think of Grace Karin as a place to shop for workwear, but the brand also has stylish, casual options you just might be missing out on. Case in point: this midi dress. The material gives it an elevated look, as does the V-neckline, rolled short sleeves, and cinched waist. The dress is great for days at the farmers market, but is conservative enough for casual days in the office. 

Best Amazon Wedding Guest Dress Deals 

For those who have a lot on their social calendar, keep reading! This list is filled with dresses for every style and occasion, including graduation ceremonies, warm-weather weddings, and garden parties. 

PrettyGarden Halter Flowy Maxi Sundress

Zesica Halter Floral Split Maxi Dress

Another great dress option is this maxi pick that comes in several fun patterns, including this floral print. It has a halter neckline, a semi-high slit, and a long skirt. The dress also has a fun stitching design on the bodice and waistline that separates it from the rest of the options on this list. You can shop it in six colors, including this orangey design. 

Merokeety Sleeveless Lace Cocktail Dress

Fancy events call for elegant dresses, and this top-rated number is one to consider. It’s made with translucent lace materials that are designed to go over the built-in slip, giving the dress a unique look. You’ll also love the timeless high neck, cap sleeves, and knee-length skirt.
