Choosing the right underwear can make a meaningful difference in your daily comfort, confidence, and the way your clothes fit. From invisible seamless options to classic cut-and-sewn styles, each type offers unique benefits depending on your preferences, wardrobe, and lifestyle. This guide breaks down everything you need to know about seamless and traditional underwear—how they're made, how they feel, and when to choose each—so you can build the perfect everyday underwear drawer.

Seamless underwear is created using advanced knitting or raw-cut fabric techniques that eliminate stitched seams and bulky finishes. Instead of traditional hems, edges are laser-cut or bonded, creating a smooth, barely-there feel against the skin.

Commando pioneered this category with raw-cut styles like the Classic Solid Thong, designed to lie completely flat under clothing.

Seamless underwear typically feels lightweight, stretchy, and flexible. Because there are no sewn-in seams, it moves with your body without bunching or rubbing. It’s ideal for sensitive skin or anyone who wants minimal texture.

One of the biggest advantages of seamless underwear is the complete lack of visible panty lines (VPL). Raw-cut edges sit flush against the skin, making seamless styles perfect under leggings, dresses, and tailored pants.

Because seamless underwear relies on stretchy, smooth fabrics, it offers a weightless feel. It moves with your body rather than against it, reducing digging and discomfort.

Many seamless designs use lightweight microfiber or performance blends, making them breathable and ideal for active days or warm weather.

Without bulky seams, stitching, or elastics, seamless underwear minimizes friction and irritation—perfect for those with sensitivities.

Traditional underwear is made using cut-and-sew construction, which means the fabric pieces are stitched together with seams, hems, and elastic trims. This allows for more structure, shaping, and design variety.

Traditional underwear can feel more secure, especially for those who prefer a more defined fit around the waistband or leg openings. The added structure can offer a cozy, supportive sensation.

Traditional designs—like the  Butter™ Hipster are great for those who prefer a classic feel or want underwear with a bit more substance. They’re also excellent for fabrics where a slightly more anchored fit is beneficial.

• Seamless: Completely invisible; best for smooth silhouettes.

Traditional: Can be invisible too, depending on the fabric, cut, and fit. Thin, soft materials can still disappear under clothing.

• Seamless: Weightless, soft, zero irritation.

• Traditional: Slightly more structure with a secure feel.

• Seamless: Often has more stretch and adapts to a wider range of body shapes.

• Traditional: Offers consistent shape and a more sculpted fit.

Both styles are durable when crafted with high-quality fabrics, but seamless underwear requires proper washing to prevent raw edges from wearing prematurely.

• A smooth, invisible look under fitted clothes

• Lightweight, minimal-feel garments

• Maximum flexibility and stretch

• Underwear that feels like “nothing”

• Ideal comfort for sensitive skin

• A more classic, structured fit

• A defined waistband or leg opening

• Underwear with additional shaping or support

• A slightly more anchored feel under clothing

Most wardrobes benefit from a combination of styles. Seamless underwear is ideal for workdays, form-fitting outfits, and warm weather, while traditional pairs offer support and comfort for everyday, lounging, or layered outfits.

• Wash cold, preferably in a mesh bag

• Avoid fabric softeners (they weaken elastane)

• Always air-dry to protect raw edges

• Can often handle machine wash cycles

• Still best washed cold

• Also air-dry to preserve elasticity and shape

Both types benefit from gentle care to extend longevity, especially in premium fabrics.

Yes—especially when made with high-quality materials like Commando’s microfiber and raw-cut fabrics. Proper washing ensures long life.

Absolutely. Many traditional styles, especially those made from thin, lightweight fabrics, are nearly as invisible as seamless options.

Seamless microfiber tends to be the most breathable and flexible, making it great for movement and activewear.

Often, yes. The absence of seams and elastics reduces irritation.

Both seamless and traditional underwear have their benefits, and the “right” choice depends entirely on your lifestyle, comfort preferences, wardrobe, and daily activities. Seamless underwear delivers unmatched invisibility and a barely-there feel, while traditional styles offer a familiar, structured fit.
