What to Wear Under a Bodycon Dress (NZ Guide)
, by Glide Shapewear , 2 min reading time
Bodycon dresses leave nothing to chance. Here's exactly what shapewear to wear underneath for a smooth, seamless finish — NZ brand, fast shipping.
Bodycon dresses are unforgiving. That's kind of the point. But between visible underwear lines, rolling shapewear, and the wrong cut bunching where it shouldn't, wearing one without the right foundation is a gamble most of us have lost at least once.
Here's what actually works underneath a bodycon dress, from someone who's tested a lot of options.
The Golden Rule: No Seams, No Lines
The most important thing you're looking for in shapewear under a bodycon dress is seamless construction. Any seam, panel edge, or lace trim will show through a fitted fabric. Full stop.
This means avoiding shapewear with thick waistbands, textured panels, or lace detailing at the hip. You want smooth, single-layer fabric with flat or bonded edges.
The Best Option: A Seamless Thong Bodysuit
A thong bodysuit is the gold standard under a bodycon dress. It covers your stomach, smooths your waist and hips, stays tucked in (unlike shapewear shorts, which can roll), and the thong cut means zero visible underwear lines from behind.
Our top picks:
Smooth Criminal Bodysuit — $69
Round neck, thong cut, seamless from top to hip. Invisible under anything fitted. This is the one to reach for when you need a completely smooth finish.
ContourOne Shapewear G-String Bodysuit — $64.95
Adds light sculpting to the mix — smooths your stomach and supports your bust while disappearing completely under your dress.
Bold Ambition Bodysuit — $54.95
The budget-friendly option that still delivers. A sleeveless, scoop-neck seamless bodysuit that does the job without the price tag.
What About Shapewear Shorts?
Shapewear shorts can work under a bodycon dress, but there's a risk: the hem line. If your dress is tight enough, you'll see where the shorts end. A bodysuit solves this completely because there's no hem to worry about.
If you do go for shorts, make sure the leg hem sits below the hem of your dress.
Do You Need a Bra Under a Bodycon Dress?
Depends on the neckline. For a low-cut or plunge bodycon, a regular bra often shows at the straps or sides. Options:
- A stick-on/adhesive bra for backless or plunge styles
- A bodysuit with built-in bust support (like the ContourOne)
- Our Barely There Bra ($39) for a wide-strap or covered neckline
The Short Answer
Seamless thong bodysuit. Every time. It solves lines, rolling, and bunching in one piece — and if you're wearing a shorter bodycon, nobody will ever know it's there.
