If you're looking for a twist on the classic LBD, allow us to introduce you to this form-fitting off-the-shoulder midi dress. It's made from a ribbed jersey that has a hint of stretch for a comfortable fit. This is the type of dress you can wear casually with a pair of sneakers and a denim jacket or formalize with strappy heels and jewelry.

"This maxi feels so soft I could wear it from the minute I get up until I fall asleep," one reviewer wrote. "It fits as expected and flows beautifully in the wind. The dress fits off the shoulders and beautifully features the décolletage."

For those who prefer bright colors in the summer, check out this fit-and-flare mini with flutter sleeves and a square neck. It has exposed seams around the waist and down the front of the torso, and it has convenient side pockets. You can wear it to brunch on the weekends, to the office during the week, and even to a summer wedding.

"I am so impressed with this dress," a shopper said. "I was not expecting it to feel and look so nice! The fit is really flattering, and it has pockets. I love the versatility of this dress, and I think I'll be buying a few more in different colors."

Another colorful option, this midi slip dress from The Drop comes in tons of bold prints and solid colors. It has a V neckline in the front and back, adjustable spaghetti straps, and slits on the sides. Plus, it's made from machine-washable polyester and elastane material that feels cool and silky, shoppers say.

"Love this dress," a reviewer shared. "Doesn't feel or look cheap, which considering the affordable price could have easily been a possibility. The fabric has a silky appearance and doesn't have that tell tale shiny polyester look. Dress this up with strappy stilettos, a leather jacket, and some great jewelry for a perfect date night dress, or a jean jacket and trainers for a casual daytime look."
