The [open] has become a must-have for those who want to enhance their curves without an artificial effect. A well-designed [open] helps naturally lift the buttocks, structure the silhouette, and improve the look under fitted clothes.
Unlike a classic underwear, the [open] acts on projection and curve. The goal is not to flatten but to support intelligently: a [open] can thus create a discreet lifting effect, more harmonious and more ānatural.ā
Summary
1) Why choose a [open]?
Choosing a [open] means seeking a more flattering look under clothes without changing your body shape. A [open] can improve posture, lift the buttocks, and give a more balanced silhouette daily.
A well-chosen [open] often helps to: enhance the curve, smooth transitions (hips/buttocks), and boost confidence, especially under a dress, jeans, or a fitted skirt.
If your goal also includes a smoother stomach, a high-waisted [open] can be interesting. To learn more about the flat stomach effect (and the differences between constructions), you can consult this guide: The best flat stomach shaping bodysuit: comparison, reviews & full test.
2) The different types of [open]
1- Push-up briefs for the buttocks
The āpush upā version emphasizes projection: the [open] is cut to support under the buttocks and create a more visible curve. Itās a good choice if you want an immediate effect under a fitted outfit.
2- Shaping briefs with lifting effect
Here, the [open] combines shaping + abdominal support. It is often called a shaping panty with a lifting effect because it helps smooth the lower belly while lifting the buttocks.
3- Shaping shorts with a rounded buttocks effect
More covering, the shorty often smooths transitions on the lower body better. This type of [open] is practical if you wear tight clothes and are looking for a more uniform look.
3) How does a [open] work?
The secret of a [open] lies in its construction: targeted compression zones, tension under the buttocks, and ergonomic cut. A well-designed [open] slightly pushes the volume upward instead of flattening it.
In practice, a [open] works by creating support āunder the curveā: this is what gives that natural lift effect and a more harmonious silhouette.
4) Which material to favor?
A [open] must be elastic, breathable, and pleasant against the skin. Technical fabrics (such as stretch nylon + elastane) often offer better support while remaining comfortable.
For a discreet look, favor a [open] with flat seams or seamless finish. This reduces lines under a dress or pants.

5) Butt-lifting panty and flat belly: the combo
Many want a butt-lifting panty that also smooths the belly. In this case, high-waisted shaping is often the best option: it helps smooth the lower belly, structure the waist, and enhance the contrast with the hips.
The idea is not to ācompress fully,ā but to achieve a cleaner silhouette: an effective butt-lifting panty must remain wearable daily. If you are looking for a more covering alternative, shaping shorts are sometimes the best compromise.

7) How to choose your butt-lifting panty well?

Before buying a butt-lifting panty, ask yourself these questions:
1- What level of support are you looking for?
Choose between light support (daily comfort), moderate (visible effect under fitted clothing), or more structuring (marked lifting effect). The right support should hold without discomfort.
2- Do you also want a flat belly effect?
If you want to smooth the lower belly in addition to the curve, favor a high-waisted butt-lifting panty for a more harmonious silhouette.
3- Will it be worn daily?
For regular use, opt for breathable material, good elasticity, and a discreet cut under your clothes.
Conclusion
The butt-lifting panty is not just a simple shaping underwear. Well chosen, a butt-lifting panty helps enhance the curve, improve the silhouette, and achieve a cleaner look in your clothes.
