Your wedding dress might be the biggest fashion show-stopper of the day, but what you wear underneath is just as important. This is all the more true if your dress errs on the side of form-fitting—which is what seamless underwear was made for. Designed to keep visible panty lines (aka, VPL) at bay, seamless underwear comes in a variety of styles and materials to keep you feeling fresh, supported, and confident. Plus, their discreet presence will leave you worrying about one less thing on the big day.
When researching the best seamless underwear for your wedding day, we looked at various styles, fabrics, and designs and carefully considered construction, special features (like tummy control and period-proof lining), and comfort. Plus, we tapped two underwear experts—Dr. Shaula Alexander Yemini and Noa Arias, the co-founders of Bloomers Intimates—to learn more about the importance of seamless bridal underwear.
“You don’t want panty lines distracting from the elegant look of your dress,” says Dr. Yemini. She adds that comfort is key when looking for seamless underwear for your wedding. "You wear your dress for hours, so the last thing you want to do is have to fix a wedgie or pull up panties that slid down or rolled up"

What to Look for In Seamless Underwear
“First, your underwear must be comfortable,” says Dr. Yemini. She notes that you don't want to have to adjust your undergarments throughout the wedding—it may also may you feel self-conscious
Dr. Yemini says to look for seamless underwear options that are compatible with your dress, whatever the style may be. Seamless underwear is especially important if your dress is form-fitting or made of a clinging material, like silk.
What is seamless underwear?
“I used to think that seamless underwear is underwear that lacks actual seams and is just cut straight from the cloth, but that’s actually not possible,” says Noa Arias, co-founder of Bloomers Intimates. “Every pair of underwear has to be constructed with at least one seam, so the practical definition of seamless underwear is that it eliminates visible seams showing under clothes,” she adds. “The worst seams are the ones around the bottom of your underwear,” Dr. Yemini adds, noting that those are the ones that typically cause visible panty lines.
Do seamless underwear show lines?
Dr. Yemini says seamless underwear won’t show lines when made correctly and with the proper fit. “When there are no seams digging into your rear, there are no panty lines showing,” she notes.
Can you wear seamless underwear with a silk dress?
“Of course,” says Dr. Yemini. “Silk dresses are a great way to highlight the benefit of seamless panties—it looks as if you aren’t wearing any underwear at all,” she adds.
Do you have to wear underwear under a wedding dress?
Both Dr. Yemini and Arias say it depends on personal preference but they like err on the side of wearing something—it's important to feel comfortable throughout a long day of activities. “I would highly recommend it for some light support,” says Arias.
