The Most Common Undergarment Mistakes (and How to Fix Them)

Undergarments are the foundation of every outfit. No matter how stylish your clothes are, the wrong undergarments can ruin the look, make you uncomfortable, and even affect your confidence. At Underties, we believe that knowing what not to do is just as important as knowing what to buy.

Here are the most common undergarment mistakes people make—and, more importantly, how you can fix them.

1. Wearing the Wrong Bra Size

Studies show that most women wear the wrong bra size without realizing it. A too-tight band can cause discomfort, while a loose fit doesn’t provide proper support.

• The Fix: Get professionally measured at least once a year, or measure yourself at home with a flexible tape. Look for bras that fit snugly but not painfully, with straps that don’t dig in.
  
  

2. Visible Panty Lines (VPL)

Few things can ruin a sleek outfit faster than visible panty lines. It can happen with fitted dresses, pajama sets, or skirts.

• The Fix: Invest in seamless underwear or thongs for outfits made with body-hugging fabrics. For everyday wear, choose panties with laser-cut edges that lay flat against the skin.
  
  

3. Ignoring Outfit-Appropriate Undergarments

A lacy bra under a sheer white shirt or dark panties under light-colored pants can throw off your look.

• The Fix: Match your undergarments to your outfit. For light clothing, stick to nude shades that blend with your skin tone. For sheer or low-cut outfits, consider strapless bras or camisoles for a polished finish.
  
  

4. Overlooking Comfort for Style

Many people buy undergarments based only on looks and regret it when they end up uncomfortable after an hour.

• The Fix: Balance comfort with style. Today’s designs offer both—wireless bras, breathable fabrics, and stylish bralettes prove you don’t need to sacrifice one for the other.
  
  

5. Wearing Worn-Out Bras and Panties

Over time, elastic stretches, fabrics thin, and undergarments lose their shape. Wearing worn-out undergarments not only looks bad but can also affect comfort.

• The Fix: Replace bras every 6–12 months (depending on frequency of use) and panties every year or as needed. If your bra straps slip or the band rides up, it’s time for a replacement.
  
  

6. Not Washing Undergarments Properly

Harsh washing cycles or skipping proper care can quickly damage delicate fabrics like lace or silk.

• The Fix: Hand-wash lingerie whenever possible. If using a machine, place them in a mesh bag, use cold water, and avoid high-heat drying. Air-drying is the best way to make them last longer.
  
  

7. Forgetting About Shapewear Fit

Shapewear that’s too tight can be uncomfortable and even affect your posture. Shapewear that’s too loose won’t serve its purpose.

• The Fix: Always try shapewear before buying. It should feel supportive, not suffocating. Opt for modern lightweight designs that enhance your shape without limiting movement.
  
  

8. Overlooking the Role of Undergarments in Confidence

Sometimes the biggest mistake is not realizing how much undergarments affect how you feel. A well-fitting set can make you feel more confident, even if no one else sees it.

• The Fix: Invest in undergarments that make you feel good, not just ones that look good. Choose colors and styles that reflect your personality.
  
  

Bonus Tip: One Size Does Not Fit All

Every body is unique. What works for one person may not work for another. The biggest mistake is assuming there’s a “universal fit.”

• The Fix: Take time to understand your body type and needs. Whether you need extra support, breathable fabrics, or flexible cuts, there’s an undergarment designed for you.
