10 Plus Size Casual Thanksgiving Outfits for a Relaxed Holiday

Not every Thanksgiving is a dress-up affair. Some are spent watching football, playing games in the backyard, helping in the kitchen, and lounging with family.

Dressing casually for Thanksgiving as a plus-size woman comes down to one core principle: start with comfortable basics like jeans, leggings, and knits, then add one fall touch so the outfit still feels festive.

Here are 10 plus size casual Thanksgiving outfits for laid-back family gatherings, football Sundays, and Friendsgiving.

1. Flannel Shirt with Black Leggings

A plaid flannel with leggings is cozy, easy, and perfectly fall.

Buying guide

• Red, rust, or green plaid flannel shirt
• High-waisted fleece-lined leggings
• Black fitted tank
• Ankle boots
• Crossbody bag

Styling tips: Wear the flannel open over a tank for a long vertical line. Choose a flannel that covers the hips for balance. Leggings with a thick waistband stay put.

2. Football Jersey with Jeans

If Thanksgiving means football in your family, rep your team.

Buying guide

• Plus size football jersey or team sweatshirt
• Dark wash straight-leg jeans
• White sneakers
• Baseball cap
• Small hoops

Styling tips: Do a front tuck to add shape to a boxy jersey. Choose jeans with stretch for comfort after the meal. Sneakers keep it relaxed.

3. Oversized Sweater with Biker Shorts and Boots

For warmer Thanksgiving locations, an oversized sweater with biker shorts is effortless and comfy.

Buying guide

• Oversized knit sweater
• Biker shorts
• Slouchy ankle boots or sneakers
• Crew socks
• Claw clip

Styling tips: The sweater should cover the top of the shorts. Choose biker shorts long enough to prevent chafing. This works best in mild weather.

4. Graphic Fall Sweatshirt with Mom Jeans

A cute fall or Thanksgiving graphic sweatshirt is playful and casual.

Buying guide

• Fall or “Thankful” graphic crewneck sweatshirt
• High-waisted mom jeans
• Chunky sneakers

Styling tips: Do a half tuck for shape. Mom jeans with stretch are comfortable for sitting. Choose subtle graphics for a more stylish look.

5. Shacket with a Tee and Jeans

A shacket is warm and easy, layering over a basic tee for a relaxed outfit.

Buying guide

• Plaid or solid shacket (tan, rust, or olive)
• White or black fitted tee

• Chelsea boots
• Gold hoops

Styling tips: Wear the shacket open for a lengthening line. Choose a relaxed but not oversized fit. Tuck the tee in front to show your waist.

6. Henley Top with Corduroy Pants

A waffle-knit Henley with corduroy pants is cozy, casual, and fall-ready.

Buying guide

Styling tips: Leave the top buttons open for a V-neck. Tuck the Henley in and add a belt. Corduroy with stretch is comfortable all day.

7. Puffer Vest with a Flannel and Jeans

For outdoor activities like a family walk or a Turkey Trot, a puffer vest keeps you warm.

Buying guide

• Olive or black puffer vest
• Plaid flannel shirt
• Dark wash jeans

Styling tips: A vest keeps your core warm without bulky sleeves. Let the flannel hem peek out below. Choose a vest that hits at the hip.
