How to Wear a Bodysuit Under a Bodycon Dress (Shapewear Tips)

A bodycon dress follows your curves closely, which is exactly what makes it look good and also what makes it unforgiving of anything underneath that creates bulk, lines, or shifting fabric. Unlike a flowy maxi or an A-line where undergarments can hide easily, a bodycon shows everything beneath it.

The right shapewear smooths your silhouette so the dress drapes the way it's meant to. The wrong shapewear means you spend the whole night pulling at your dress. Here's how to get it right.

Choosing the right shapewear style

Bodysuit: the best option for bodycon

For a bodycon dress, a bodysuit is almost always the right choice. It's a single continuous piece that covers your entire torso without any waistband to create a visible line or roll. No edge at the waist means nothing to see through the dress.

Look for:

Thong or no-show bottom to prevent visible panty lines across the seat

Open-bust design if you want to wear your own bra, or a built-in underwire option

Moderate-to-firm compression (very firm compression can cause a bodycon to bunch in odd places)

Seamless or flatlock construction with no ridges or seam lines visible through the fabric

High-waist shorts: for extra coverage

If your bodycon dress is on the shorter side and you want thigh coverage as well as tummy shaping, high-waist shaping shorts extend the shaping effect down to mid-thigh and stop the dress from riding up. Make sure the shorts sit at least 2-3 inches shorter than the dress hemline so they stay hidden.

What to skip

Avoid traditional high-waist briefs under a bodycon. The waistband and leg openings both create visible edges through the fabric. Also skip shapewear with heavy front seaming: even through thick bodycon fabric, these seams can show under certain lighting.

How to avoid visible lines

Go seamless throughout

Choose shapewear with seamless or bonded construction. Sewn seams create ridges; bonded edges sit flat against the skin. Run your hand over a seamless bodysuit and you should feel an even surface from top to bottom. That's what the dress will feel when it drapes over it.

Match your shapewear colour to your skin tone

Through fabric that's even slightly sheer or stretchy, the colour of your shapewear matters. Nude matched to your skin tone is the most invisible option. Black shapewear under a black dress works too, but avoid white or light shapewear under anything body-hugging: it can read as a lighter area through the fabric.

Check for lines before you leave

Put your full outfit together and do a 360-degree mirror check in natural light. Sit down, bend forward, turn to the side. Look at the waist area, the seat, and the leg openings. If you spot any lines, adjust the shapewear positioning or switch to a different style.

Use fashion tape for extra security

If your bodycon tends to shift or cling, a few strips of double-sided fashion tape at the neckline and hemline keep everything in place. This is especially useful with a deep neckline: tape prevents it from moving and exposing the top edge of your shapewear.

HEYSHAPE picks for bodycon dresses

The HEYSHAPE 360° Snatch Bodysuit works well under bodycon dresses for a few specific reasons:

Fully seamless construction: no visible lines, seams, or edges through tight fabric

360° shaping panel: smooths the entire midsection from all angles, not just the front

Moderate-to-firm compression: enough to smooth and shape without creating unwanted bulk under the dress

Thong bottom: no visible panty lines, even under the tightest bodycon

Open-bust design: compatible with any bra, including stick-ons and plunge styles

Multiple nude shades: matches a wide range of skin tones for minimal visibility under sheer or stretch fabrics

Outfit ideas

The little black dress

Pair with a black seamless bodysuit. The matching colour means even if the dress is slightly sheer at the waist under strong light, the shapewear stays invisible. Add nude heels and keep jewellery minimal.

The fitted midi dress

A midi-length bodycon works for work, weddings, and evenings out. Under a fitted midi, a bodysuit or high-waist shorts both work. Go with the bodysuit if the dress fits snugly at the waist and hip; shorts if you want thigh coverage.

The date-night mini

For a mini bodycon, a thong-bottom bodysuit is the right call: no leg lines, and the thong stays hidden if the dress rides up slightly. Moderate compression lets the dress show your natural shape, just with a smoother surface.

The slinky wrap dress

Wrap bodycon dresses often use stretch fabric that drapes close to the body. A seamless bodysuit in your exact skin tone works best here: it stays invisible under the wrap fabric and stops the dress from shifting open at the waist.

Getting the fit right

Choose the right style for your dress length, match your shapewear colour to your skin tone, and check for lines before you go out. Those three steps cover most of what goes wrong with shapewear under bodycon dresses. The rest takes care of itself.
