Let’s get started!
OUR TOP PICK
We begin our list with this gorgeous off-the-shoulder sequin dress.
We love the line of the neckline and how it wraps around the body to dip a little lower at the back, without being too low.
The skirt comes to mid-thigh and is gathered at the front to give it a little more shape.
The wine red shade is our favorite but there are several other colors for you to choose from.
We would suggest avoiding a necklace but this dress is perfect for other types of jewelry such as dangly earrings and delicate bracelets.
This dress features a lace layer over the top of a shorter dress.
The lace layer extends a few inches below the main dress and covers the shoulders, making the dress look more demure and covering than it really is.
It’s a great mix of sexy and elegant.
You have many different colors to choose from but we prefer the darker colors in this dress.
Dark green, navy, and black are definitely our favorites!
There is so much to love about this dress and it is sure to turn heads!
It will leave your right shoulder bare and has an eye-catching slit in the left shoulder that adds some real style to the dress.
We love the gathered waist and how this leads down to a ruched skirt.
Although the skirt comes to below the knee, the way it folds allows you to flash a little bit of thigh.
Match the dress with some heels, a clutch bag, and some sparkly jewelry for the finishing touches.
Everyone loves a little black dress and this one will be no exception.
It’s always a safe bet for a party when you are stuck for something to wear and despite being a classic, it’s still sexy and elegant.
The highlight of this black dress is the long mesh sleeves and the straight neck and backlines.
Although this dress is available in a large number of other colors, we really recommend black.
There are a few black options available, however, as some have dots on the sleeves and others have butterflies.
Stick to black and choose whichever appeals to you!
We love velvet as a material for eye-catching dresses.
It’s a material that is often overlooked in favor of polyester and lace but it always stands out and is perfect for a sexy dress.
This dress has a ruched effect so it looks like it wraps around the body.
The low neckline is perfect for a pretty necklace and we love how the neckline mirrors the shape of the hem.
Sexy dresses don’t have to be short, as this ankle-length dress proves!
Although the cut is simple, it’s made more eye-catching by being covered head to toe in sequins.
The top of the dress is strappy and has a deep V-cut whereas the skirt has a split that reaches to the upper thigh.
This dress is sure to turn heads and should be paired with some strappy heels. Add a necklace for the finishing touches.
We love how youthful this dress is!
It’s great for anyone in their late teens or early twenties to wear due to its playful style and look.
The top of the dress features thick straps and a wrap-style that flows down to a fitted waist.
The skirt is pleated and flares out and falls to just above the knee.
This is a great dress for pairing with a short jacket and a few delicate pieces of jewelry.
Although this isn’t as classically sexy as some of the other dresses on this list, we still feel it’s worth including and is sexy in its own right.
It features a beautiful floral lace layer that looks especially pretty in the light-pink, blush color.
It’s fitted at the waist and has a ribbon belt that you can tie into a bow at the back or the front.
It also has a high neckline with short sleeves, so you don’t need a necklace with this dress.
It will look great with some sparkly earrings and high heels.
Off-the-shoulder dresses are always eye-catching!
When worn, the neckline becomes a straight line across the chest and sleeves that looks both sexy and elegant.
It’s the hemline of the skirt that is our favorite feature, however.
It’s asymmetrical with the back of the dress being several inches longer than the front.
We love this style of skirt and this dress is a great example of it.
Wear with some high heels or strappy sandals and don’t be afraid to choose one of the bolder colors!
Satin has always been seen as a sexy and luxurious material due to how smooth and sleek it is.
It feels great against the skin and is very flattering as a dress material.
The back of the dress is pretty low and features a drawstring closure so you may need some help to get this dress fitted correctly.
The front of the dress features adjustable spaghetti straps and a low V-cut neckline.
It also has a split that comes to mid-thing.
Although this might look like separates, it is a dress.
The top half features a lace layer over a camisole-type layer and elbow-length sleeves.
The skirt is in the pencil skirt style and hugs the hips and thighs with a slinky and smooth material.
The two halves are divided by a decorative belt.
The dress is available in many different colors but we love the silver and gold options the most. These colors are sure to turn heads.
If you prefer your dresses to have high necklines but to still be short, then this dress is a great choice for you.
It has a crew neck top with long and puffy sleeves.
The skirt falls to the mid-thigh level and the dress is tied together with a fabric belt that will allow you to cinch the waist.
This dress is great for giving you several shoe options.
You can wear heels, of course, but this dress will also work with ankle boots, knee-high boots, or sandals.
For our final three options, we’ve moved away from dresses to instead focus on rompers and jumpsuits.
These can be just as sexy and elegant as any dress can be and we love how comfortable they are!
Our first romper features forearm-length sleeves and pant legs that are wide and billowing.
This makes the fitted and belted waist stand out even more and adds a wonderful shape to your body.
An easy way to make any type of clothing stand out is to add as many sequins as possible.
This romper suit follows this idea and also has a low V-cut neckline that is perfect for an equally sparkling necklace.
It has wide legs and a sparkly belt to ensure the suit still gives you a good waistline.
Our final outfit is this sexy off-the-shoulder jumpsuit.
It’s more fitted than the previous jumpsuits and the bare shoulder is sure to turn heads.
The jumpsuit is available in several colors and honestly, we love them all!
Add some heels and you will have a gorgeous and sexy look.
