In my experience, velvet feels warm and hides undergarment seam lines, so it’s a great material for a bodycon winter dress. This one is form-fitting with a mock neck, ruching at the waist, and lace detailing at the hem. Pair it with stilettos, and you’re ready for any late-night party.

Satin slip dresses can be worn year-round with the right accessories. The low waistline and asymmetrical bottom create a unique look that’ll make you stand out this holiday season. Pair it with a shawl or cropped sweater, dainty jewelry, and heels.

A red mini dress is practically a must-have for holiday parties. This A-line style can be dressed down with flats and a cardigan for a casual holiday dinner or dressed up with heels and jewelry. You can also get this boat-neck dress in other holiday colors, like maroon or dark green.

"This dress is pretty universally flattering thanks to the wrap silhouette," said Senior Commerce Manager Mackenzie Dunn. "The crushed velvet is ideal for fall or even a holiday party. I also appreciated the flutter sleeves and slit that both added some drama to the dress."

Dunn noted that this dress held up in the wash after being washed on cold and line-dried. She added that it runs slightly big. Keep in mind that the dress is made in 36 colors; each size has only around 10 or more colors in stock.

Sweetheart necklines are sweet and feel nostalgic. While this one’s not on sale, it costs under $50 at retail. The sleeve straps are tied into cute bows at the shoulders, and the dress has a lovely flared skirt. Get it in bright red for a holiday party and I bet you’ll get loads of compliments.

Plaid for the holidays is classic, but the bow ribbons on the front makes this pick so on trend. The silhouette is pretty loose-fitting, so you’ll feel comfy all day and night (and can wear underlayers if it’s cold!). Pair it with loafers or flats for a more casual look, or accessorize with jewelry and heels to dress it up.

We love the puff sleeves and tulle details on this dress. The smocked material around the chest is stretchy for an overall comfy but cute style.

If your holiday party calls for cocktail attire, we like the balloon sleeves and on this numer. The brand claims the ruching helps visually smooth undergarment seams and shapewear lines. Its dramatic lantern sleeves can be worn on or off your shoulders, depending on your preference.

This off-the-shoulder sweater dress will work for a variety of occasions, from Thanksgiving dinner to winter weddings—several online reviewers even wore it to their engagement parties.

A cozy, cable-knit sweater dress is perfect for Thanksgiving dinner or a chill holiday hangout.

"The length falls right around mid-knee, which makes it versatile to pair with sneakers or boots. It feels well made, comfortable, and practical."

Park noted that this dress pilled a bit after washing, and recommends washing it on gentle and air-drying it for the best results. She added that it fits true to size.

One of our editors said she was “blown away” by this dress’ thick, plush fabric that looks expensive. “I love that it comes with a matching shrug, making it a versatile addition to my fall and winter wardrobe,” she shared.

Nothing says fall like sweaters and plaid, so this dress is perfect for Thanksgiving dinner. The dress also comes in green or red with the plaid layer, which feels very holiday-esque. Pair it with tights and boots on a chilly day for a cozy but cute vibe, or dress it up with heels for a date night or holiday party.
