What to Wear Under a Bodycon Dress for a Smooth, Line-Free Look

Under a bodycon dress, wear a layer whose edges won't show: a shaping bodysuit for one smooth line from bust to hips, or high-waist shaper shorts if you only want the waist, hips and thighs smoothed. Match the shade to your skin under light colours, choose black under black, and check every edge in daylight before you go.

Bodycon is the least forgiving cut there is, not because of anyone's body but because the fabric follows everything underneath it: underwear, bra hooks and the edge of whatever shapewear you chose. You can, of course, wear one with nothing special underneath. If you want a smooth line, here's how to choose.

Bodysuit or shaper shorts: which is better under a bodycon?

Our snatched bodysuit is made for this kind of dress: a one-piece torso shaper with extra compression at the core and waist, style lines that support the bust, and rounded butt pockets so the back of the dress keeps its shape instead of looking flattened. It comes in black or nude. The high-waist tummy tucker is a seamless shaper short with a silicone grip band and a no-roll waistband, which is what you want under a long, fitted midi when you'll be sitting and standing all night.

Some people wear both under a body-hugging midi. That works, but it's a lot of compression for a long evening, so wear the pair at home for an hour first. Our guide on how to layer shapewear covers the order, and tummy tucker vs shapewear vs bodysuit compares the pieces in general.

Where do lines show under a bodycon dress?

Check these five places, in this order:

1. The bum. Underwear leg openings are the most common line. Seamless or laser-cut underwear, or a shaper that sits smoothly over it, solves it.
2. The upper back. A bra band and its hooks show through thin jersey. A bodysuit covers the area; otherwise choose a smooth, wide-band bra.
3. The thigh. The leg edge of shaper shorts shows if it ends where the dress is tightest. Ideally it sits where the dress has a little ease.
4. The waist. A waistband that folds or rolls shows as a ridge. A no-roll waistband, or the next size up, fixes it.
5. The bust edge. Under strapless or off-shoulder bodycons, the top of a bodysuit can peek out.

The test: put the full outfit on and record a short phone video in daylight, walking towards and away from the camera, then sitting down. Lines that are invisible in a bedroom mirror under a warm bulb often show up on video. For more on hiding edges, read how to make shapewear invisible.

How do fabric and length change your choice?

Not every bodycon behaves the same way.

• Thin jersey or ribbed knit shows the most. A bodysuit is usually the cleaner choice because its edges sit at the leg line and shoulders, away from the tightest stretches of fabric.
• Thick bandage or scuba fabric hides more. Shaper shorts, or even just seamless underwear, may be all you need.
• Mini length: shorts with thigh coverage can peek out when you sit, or when you climb into a cab or an auto. A bodysuit avoids that.
• Midi or maxi with a slit: check which side the slit falls on and how high it opens when you walk. The shorts' edge shouldn't flash through it.

Size matters as much as style. A shaper that's too small rolls, digs in and shows more, not less. The bodysuit comes in S-M, L-XL and 2XL-3XL; check your bust, waist and hip measurements against the bodysuit size chart, and if they fall across two sizes, go by the larger one.

Should you wear stockings with a bodycon dress?

For a winter party, an evening reception or a cold office AC, yes. They look polished and keep you warm. Skin-colour stockings make your legs look even-toned without looking covered; black stockings suit black, jewel-tone and darker dresses and look more deliberate.

Our anti-scratch stretchable stockings are full-length and waist-high, with a silicone grip band, and come two pairs to a pack: one skin and one black, two skin, or two black. If you're also wearing a bodysuit, try the layers both ways. Stockings under the bodysuit hide the stocking waistband for a smoother hip; stockings over the bodysuit make bathroom breaks simpler.

Which bra goes under a bodycon?

• High neck or crew neck: a smooth T-shirt bra, with a bodysuit over it if you want the band covered.
• Square or sweetheart neck: a balconette or strapless bra, so cups don't show at the neckline.
• Strapless, off-shoulder or backless: a stick-on option from the sticky bra collection, paired with high-waist shorts rather than a bodysuit if the bodysuit's top would show.

Choose the bodysuit for thin, short or very fitted dresses, the shorts for longer hems and long nights, and a shade that matches either your skin or the dress. Then do the daylight video test. If you can't spot an edge on your phone, nobody at the party will.

Frequently asked questions

How do I avoid panty lines in a bodycon dress?

Wear seamless or laser-cut underwear, or a bodysuit or high-waist shaper that sits smoothly over the bum so leg openings don't show. Check from behind in daylight, standing and sitting.

Can I wear a bodycon dress without shapewear?

Of course. Shapewear is a choice about how fabric sits, not a requirement, and smooth underwear under a dress in thicker fabric often gives a clean line on its own.

What colour shapewear should I wear under a red bodycon dress?

Nude close to your skin tone is safest under thin red jersey. Under thick bandage fabric, nude or black both work, since nothing shows through.

How do I stop a bodycon dress riding up when I sit?

Smooth the hem down as you sit and keep your knees together. A smooth shaper underneath helps, because the dress slides over it instead of clinging to bare skin.
