What to Wear Under White Pants: The Best No-Show Underwear for a Flawless Look
White pants are a warm-weather favorite (for good reason). They’re fresh, polished, and go with practically everything. But let’s be honest: figuring out what to wear under white pants can sometimes be tricky. Visible panty lines, sheerness, or an unflattering fit can easily take attention away from your look.
At SPANX, we believe that confidence starts with a great foundation. Whether you’re slipping into wide leg pants, slim straight jeans, or anything in between, here’s your guide to the best undergarments to wear under white pants (plus our favorite white styles to pair them with).
Why Choosing the Right Undergarments for White Pants Matters
White fabric is naturally less forgiving—it can be sheer, unflattering or highlight the outline of your underwear. That’s why choosing the right neutral, seamless, or shaping base layer is key to creating a clean, smooth look.
With our thoughtfully designed white pants for women, you can feel confident, supported, and stylish—without worrying about what’s showing through.
