5 Essential Bridal Shapewear Pieces from SPANX

On wedding day, there’s the dress—and then there’s everything that’s happening underneath it. No matter how stunning your gown is, the right foundation makes all the difference. Bridal shapewear is that behind-the-scenes magic that helps everything look smoother, sit better, and feel more secure, so you can fully focus on the moment (and not on tugging at your straps).

The SPANX® Bridal Shapewear Collection was designed with real wedding-day needs in mind—from low-back bodysuits to stay-put strapless bras to smoothing shorts that won’t show under silk. We’ve got solutions for every dress cut, compression level, and personal preference. Whether you're the bride, a bridesmaid, or a guest pulling off a tricky dress, we’ve got your back (and your waist, hips, and bust too).

With five different compression levels, SPANX shapewear lets you pick your level of sculpt—from a light, breathable hug to a total cinched-in moment. Ahead, we’re walking through five bridal shapewear must-haves, and exactly why they deserve a spot in your wedding-day wardrobe.

SPANXshape Invisible High-Waisted Mid-Thigh Short

Let’s start with a wedding shapewear classic: the mid-thigh short. The SPANXshape™ Invisible High-Waisted Mid-Thigh Short was practically made for bridalwear. It’s lightweight, ultra-smooth, and truly invisible under even the clingiest fabrics (yes, even silk or satin).

The bonded tummy panel gives you targeted shaping without bulk, and the high-waisted design keeps everything smoothed out from bust to thigh, so you can wear that body-skimming dress confidently. Bonus: the leg openings won’t dig in or roll, so your silhouette stays seamless all day (and night).

Best under:

• Sheath or mermaid gowns
• Bias-cut slip dresses
• Fitted jumpsuits

SPANXshape Plunge Low-Back Mid-Thigh Bodysuit

Deep-V neckline? Backless gown? High slit? This bodysuit handles all of it. Our SPANXshape™ Plunge Low-Back Mid-Thigh Bodysuit is a true shapewear unicorn—flexible, sculpting, and engineered for very specific bridal dress challenges.

It has built-in cups for lift and coverage, a plunging neckline that works with deep front cuts, and a low, open back that disappears under open or illusion backs. The mid-thigh short provides smoothing and light compression, and the convertible, adjustable straps give you options when your dress has an unconventional cut.

Best under:

• Deep plunge dresses
• Low-back gowns

SPANXshape Invisible Open-Bust Mid-Thigh Bodysuit

Want full-body smoothing but love your own bra? The SPANXshape™ Invisible Open-Bust Mid-Thigh Bodysuit lets you pair your favorite bra with shapewear that hugs, shapes, and stays invisible.

It features adjustable straps, edge-bonded panels for that second-skin feel, and shaping from your bra band to your thighs. The open-bust design means it’s totally versatile, especially if you already have a strapless or specialty bra you love for your wedding dress. It’s smoothing without being stiff, and flexible enough to move with you from aisle to afterparty.

Best under:

• Dresses with straps
• Gowns with built-in corsets or cups
• Any look that needs shaping plus your favorite bra
