Buying Guide: Choosing Plus Size Underpants

Sizing and Fit

You want underpants that fit just right. Always check the size chart for each brand. Sizes can change from one shop to another. Measure your waist and hips before you buy. If you fall between sizes, try the bigger one for more comfort. Look for styles with a wide waistband and stretchy fabric. These features help the underpants stay in place and stop them from rolling down. If you have a fuller tummy or hips, high-waisted briefs often give the best support.

Tip: Try different cuts, like full briefs or high-leg styles, to see what feels best for your body shape.

Best Materials for Comfort

The fabric makes a big difference in how your underpants feel. Here’s a quick look at how popular materials compare for comfort and durability:

Cotton and bamboo feel soft and let your skin breathe. Bamboo also helps keep you cool and fresh. Nylon and polyester dry quickly and last longer, but they might not feel as soft. Silk feels lovely but needs gentle care.

Styles for Everyday and Special Needs

You have many styles to choose from. Full briefs give you the most coverage and support. High-leg briefs let you move easily and feel less bulky. Thongs work well if you want no visible lines under clothes. For period days, look for absorbent briefs with leak protection. If you want a smooth look under dresses, try shaping briefs. Pick what matches your daily needs and makes you feel confident.

Common Concerns and Solutions

Preventing Rolling and Riding Up

You know how annoying it feels when your underpants roll down or ride up. You want them to stay put, no matter what you do. Here are some tips that really work:

• Choose underpants with a wide waistband, like the ones you find on yoga pants. This style hugs your waist and keeps everything in place.

• Look for flat seams, such as Merrow Activeseam stitching. These seams help stop rubbing and keep the fabric from shifting.

• Pick a cut that gives you full coverage and a secure fit. This helps your underpants stay where they should, even when you move a lot.

• Breathable fabrics, like modal with a double-layered front, add comfort and prevent overheating.

• Tag-free designs also help, as they remove a common source of irritation.

Tip: Try a few different styles to see which ones stay put best for your body shape.

Caring for Underpants

If you want your plus size underpants to last, you need to care for them the right way. Follow these steps:

1. Wash your underwear in cold water to keep the fabric stretchy and the colours bright.

2. Use gentle, plant-based detergents. Avoid bleach and harsh chemicals.

3. Air dry your underpants instead of using a tumble dryer. This stops shrinkage and helps them last longer.

4. Store your underwear in a cool, dry place. Keep them away from sunlight and moisture.

5. Hand wash delicate fabrics like lace or silk.

6. Rotate your underwear so each pair gets a break and keeps its shape.

7. Check for loose threads or stretched elastic. Replace worn pairs when needed.

8. Skip fabric softeners. They can damage the fibres and reduce moisture-wicking.

Keeping up with these habits means your favourites will stay soft, fresh, and comfy for longer.

Reducing Chafing and Irritation

Chafing and irritation can ruin your day. The right materials and design make a big difference. Here’s a quick guide:

Flat seams and soft, stretchy fabrics help stop rubbing. Modal-cotton blends feel especially gentle and reduce friction. If you have sensitive skin, chemical-free fabrics are a smart choice.

If you notice any redness or discomfort, switch to a softer fabric or a different cut. Your comfort always comes first.
