What Underwear to Wear with Leggings: Stay Seamless, Confident & Comfortable

Wearing leggings is all about comfort, flexibility, and confidence—but the wrong underwear can ruin it all. Whether you’re rocking your favorite galaxy leggings or a sleek black pair to the gym, the right underwear makes a world of difference. From visible panty lines (VPLs) to bunching, riding up, or showing through, bad underwear choices can turn a stellar look into a fashion flop.

In this guide, we’ll answer the question: What underwear to wear with leggings? We’ll also give specific tips for styling galaxy leggings, where prints, stretch, and opacity add even more to think about.

Why Underwear Matters When Wearing Leggings

Leggings hug every curve, stretch with every move, and often come in bold prints or light colors. That means your underwear can:

• Show through thin or tight fabric

• Create lines or bulges (even if your leggings are opaque)

• Shift or ride up as you move

• Distract from your overall look

Whether you’re heading to yoga or out for errands, choosing the right underwear keeps your leggings look smooth, sleek, and worry-free.

Best Types of Underwear to Wear with Leggings

1. Seamless Underwear

Best overall option. Seamless panties are designed without visible stitching, making them ideal under tight clothing like leggings.

• Why they work: No seams = no lines.

• Best for: Gym, yoga, casual wear

• Tip: Look for soft microfiber or nylon-spandex blends that move with your body.

💡 Pro tip: Seamless thongs or cheekies work especially well with galaxy leggings, where bold prints shouldn’t be interrupted by panty outlines.

2. Thongs

Minimal coverage, zero VPL. Thongs are a go-to for those who want total invisibility under leggings.

• Why they work: No fabric across the backside.

• Best for: Tighter leggings, especially light or solid colors.

• Downside: Some find them uncomfortable for long wear.

For galaxy leggings, thongs help keep focus on your cosmic print—not what’s underneath.

3. Boyshorts or Shorties (Seamless)

Full coverage with smooth edges. Great for those who don’t like thongs but still want to avoid VPL.

• Why they work: Extend past the hip crease to eliminate lines.

• Best for: Daily wear, errands, chill days

• Watch out: Choose thin, breathable fabrics or they may bunch up.

4. Commando (No Underwear at All)

Yes, going commando is an option—especially with high-quality leggings like those from GalacticLeggings.com.

• Why it works: Zero VPL, no bunching.

• Caution: Hygiene is key. Only go commando in leggings with a built-in gusset and moisture-wicking lining.

• Best for: Lounging, yoga, or when you know you’ll stay dry.

Underwear Fabrics That Pair Best with Leggings

Choosing the right type of underwear is just the start—you also want to pick the best fabric:

For galaxy leggings, synthetic fabrics like microfiber or nylon/spandex are best—they move with you and disappear under bold prints.

Underwear Colors: What to Wear Under Galaxy Leggings?

When choosing underwear color, consider your legging’s color and opacity.

• For light or white leggings: Wear nude underwear that matches your skin tone.

• For black leggings: Black or seamless thongs are perfect.

• For galaxy leggings: Since the print is often bold, you have more flexibility—but nude, black, or color-coordinated seamless options work best.

Mistakes to Avoid

❌ Wearing thick cotton briefs – They tend to show lines and absorb sweat.

❌ Choosing the wrong size – Underwear that’s too tight causes bulges; too loose bunches up.

❌ Skipping the stretch test – Always test leggings in a squat or bend to see if your underwear shows through.

What Underwear to Wear with Galaxy Leggings Specifically?

Galaxy leggings are unique—they’re eye-catching, form-fitting, and often made with stretchy polyester-spandex blends that hold color well. When wearing them:

• Stick with seamless thongs or cheekies in black, navy, or neutral tones.

• Avoid bulky seams that interrupt the print.

• Choose underwear that moves with your body during stretching or workouts.

• Go commando if your leggings have a gusset and are squat-proof.

At GalacticLeggings.com, all leggings are designed with high opacity and four-way stretch, so you can pair them with almost any seamless option—or skip underwear entirely.

Final Tips: How to Keep Everything Smooth

• ✅ Match fabric types: Soft microfiber underwear pairs best with polyester-blend leggings.

• ✅ Stay fresh: Moisture-wicking underwear is key for gym days.

• ✅ Wash with care: Use gentle detergent and air dry to preserve both leggings and underwear.

Final Thoughts

So, what underwear to wear with leggings? The answer depends on your comfort level, the activity, and the style of leggings. But in general:

• Choose seamless styles to avoid panty lines.

• Stick with stretchy, breathable fabrics.

• For galaxy leggings, prioritize underwear that won’t distract from the print.

Whether you’re heading to Pilates, running errands, or turning heads in your favorite galaxy leggings, the right underwear keeps everything smooth, confident, and distraction-free.
