You’ve spent months—maybe years—obsessing over the lace, the train, and that specific shade of ivory that makes your skin glow. But honestly? The most expensive dress in the world will look like a wrinkled sack if you don’t nail what’s happening underneath it. People don’t talk about this enough. They talk about the veil. They talk about the shoes. They rarely talk about the high-waisted compression shorts that are currently keeping your internal organs in a state of polite strangulation.
Picking what to wear under your wedding gown isn’t just about looking "snatched." It’s about being able to eat a piece of your own cake without feeling like your ribs are going to crack. It’s about not having a visible panty line (VPL) in your high-res professional photos that you'll be looking at for the next fifty years.
There’s a lot of bad advice out there. Some people will tell you to just "go commando" and call it a day. Others insist you need a Victorian-era corset. The truth is usually somewhere in the middle, depending heavily on the fabric of your dress and how much you plan on hitting the dance floor.
The Fabric Dictates the Rules
If you’re wearing a heavy ball gown with fifteen layers of tulle, you could probably wear Batman boxers underneath and nobody would know. You have freedom. But if you’ve opted for a silk crepe sheath or a bias-cut slip dress? Well, God help you. Those fabrics are basically sentient; they cling to every seam, every bump, and every poor decision you've ever made.
For thin, clingy fabrics, seamless is the only way to go. Brands like Commando or Spanx have refined the "raw cut" edge which basically melts into your skin. You want to avoid lace, bows, or anything with a thick elastic waistband. Even a "seamless" thong can sometimes create a ridge if the fabric of the dress is lightweight enough. In those cases, some brides actually opt for a seamless bodysuit to create one continuous, smooth line from the bust to the mid-thigh.
Then there's the color. Everyone thinks you should wear white under a white dress. Wrong. White fabric under white fabric often glows like a neon sign. You need "nude-to-you" tones. You want the underwear to disappear against your skin, not match the dress. If you have a darker skin tone, look at brands like Nubian Skin or Heist, which actually offer a range of shades that go beyond "pale beige."

Let’s Talk About the Bra Situation
Most modern wedding gowns come with cups sewn in. If yours does, and you’re a B-cup or smaller, you might be able to skip the bra entirely. It’s a liberating feeling. Truly.
But for those of us who need a bit more structural integrity, the "sewn-in cup" is often a lie. It provides coverage, sure, but zero lift. If you’re a D-cup or above, you’re looking at a few options:
- The Longline Bra: This is the GOAT for strapless dresses. It anchors to your waist, so the weight of your bust isn't just pulling the top of the dress down all night.
- Boob Tape: It sounds terrifying. It kind of is. But if you use something like Brassybra or Booby Tape correctly, it’s a miracle for backless or deep-plunge gowns. Just... please, for the love of everything, do a patch test 48 hours before the wedding. You don't want a geometric rash on your chest during your vows.
- The Bodysuit: A plunging back bodysuit with wire support is the holy grail, but they are notoriously hard to fit. You’ll likely need to try on five different brands to find one that doesn't create a "butt shelf" or dig into your shoulders.
Shapewear: Friend or Foe?
Shapewear is polarizing. Some people find it empowering; others find it a tool of the patriarchy. Regardless of your political stance on spandex, you need to consider the practicalities.
You are going to be in this outfit for 10 to 14 hours. You will be hugging people. You will be sitting down for dinner. You will be trying to use a bathroom stall while three bridesmaids hold up five pounds of satin for you. If your shapewear is so tight that you can't take a full breath, you’re going to have a panic attack by the time the appetizers roll around.
When choosing what to wear under your wedding gown, think about "smoothing" rather than "transforming." You aren't trying to lose two dress sizes in ten minutes. You just want a smooth canvas. Look for high-waisted shorts that end just above the knee if you’re worried about thigh chafing—a very real "wedding day ruined" scenario.

Dealing with the "Restroom Logistics"
This is the part the bridal magazines skip. How do you pee?
If you’re wearing a full bodysuit or high-waisted shapewear, you have two choices:
- The "Gusset Opening": Some shapewear has a hole in the crotch. It’s a design choice that requires a certain level of... athletic aim.
- The Full Strip: You have to take the whole dress off.
Neither is ideal. This is why many professional stylists recommend high-waisted shorts instead of a full bodysuit. You can pull them down relatively easily without needing a team of engineers to get you back into your dress.
The "Second Skin" Layer
For brides wearing heavy lace or beaded gowns, there's another issue: itching. Beading is gorgeous, but the thread used to attach those crystals can be scratchy as hell against your ribs. A very thin, lightweight slip or a smoothing camisole can act as a barrier.
Don't forget the slip. A traditional A-line or ball gown often needs a crinoline or a petticoat to keep its shape. Without it, the fabric can collapse between your legs when you walk, making you trip or look like you're struggling through a swamp. A simple silk slip can also prevent the dress from "static-clinging" to your legs as you move down the aisle.

What Most People Get Wrong About Sizing
There is a weird temptation to buy shapewear a size too small. Don't. Please.
If it’s too small, it will roll down. There is nothing more distracting than a rolling waistband that settles into the thinnest part of your waist and creates a literal spare tire where there wasn't one before. Buy your actual size. If you're between sizes, go up. The goal is a smooth line, not a vacuum-sealed effect.
Actionable Tips for Your Final Fitting
You shouldn't be deciding on your undergarments the morning of the wedding. That is a recipe for a meltdown.
- Bring the gear to the seamstress. You need to wear the exact bra and underwear you plan to use during your alterations. Even a 2mm difference in bra padding can change how the bodice of the dress sits.
- The "Sit and Dance" Test. Put on the undergarments. Sit in a chair. Now, try to do a bit of a shimmy. If the bra pokes you or the shorts roll down, they’re fired.
- Check the lighting. Step into natural light and have someone take a photo of you from the back. Flash photography can make some fabrics transparent, revealing the "hidden" seams of your shapewear.
- Break them in. Wear your shapewear around the house for an hour or two a week before the big day. It softens the elastics just enough so they aren't "biting" into you on the day of.
Ultimately, what you wear under your wedding gown should be invisible and forgotten. If you aren't thinking about your underwear by the time the ceremony starts, you’ve done it right. You’ve got enough to worry about—like not tripping over your veil or remembering your spouse's middle name—without your Spanx trying to stage a coup against your ribcage.
Prioritize breathable fabrics like cotton blends or high-tech moisture-wicking synthetics, especially for summer weddings. If you're prone to sweating, a little bit of anti-chafing balm (like Megababe) on your inner thighs under your shapewear is a pro move. Comfort is the true secret to looking beautiful; a bride who isn't pinching her waist every five seconds is a bride who actually looks happy in her photos.
