Over 12 years of working as a styling coach, I've learned one hard and fast rule: the less fabric on an evening gown, the more complex the engineering underneath. When a client brings me a silk dress with complex geometry, my first thought isn't about the shoes. My first thought is about the architecture of the weight distribution. The ideal underwear for a dress with side cutouts - It's not a question of modesty, it's a question of physics.

Have you ever noticed how actresses move so freely on the red carpet in dresses that seem to be hanging on by a thread? The secret is that the base layer acts as a hidden exoskeleton. We covered the basic principles in more detail in our The complete guide to the perfect lingerie for a low-cut dress , but today we'll go beyond clichéd advice like "buy seamless panties." We'll tackle this challenge like true style engineers.
Silhouette Engineering: Why It's So Difficult to Choose Lingerie for a Dress with Side Cutouts
A dress with cutouts disrupts the normal physics of fabric weight distribution on the body. Typically, fabric rests on the shoulders, chest, and hips, falling downward. But as soon as exposed areas appear at the waist or ribs, the balance collapses. The fabric begins to rise or sag, distorting the designer's intended silhouette.
I was once preparing a client for a black-tie event. She was wearing a stunning dress, costing around €1,500, with a deep cutout waist. Everything fit perfectly during the fitting. But as soon as she slipped on her favorite seamless microfiber panties, the cutouts started to slide. The smooth fabric of the lingerie acted like a steamroller: the silk dress began to slide over her with every step, gathering into unsightly folds. We had to quickly change the concept.

The concept of "invisible styling" states that the hidden layer should be a structural framework, not just a hygienic layer. Necklines require perfect fabric tension, which is impossible to achieve with regular underwear, even the thinnest.
The Biggest Illusion: Why Classic Silicone Pads Will Ruin Your Evening
Let's talk about the elephant in the room: thick silicone cups with Velcro fastenings and a lace-up closure. For years, the mass-market industry has convinced us that this is the one-size-fits-all solution for any revealing outfit. As a practicing stylist, I declare: this is the worst investment in your evening look.
"Silicone push-up bras create the illusion of support for exactly 15 minutes while you stand in front of the mirror in a cool dressing room. As soon as you step out, the countdown to embarrassment begins."
According to internal statistics from private styling agencies (and my personal experience), about 80% of these pads lose their stickiness after 3-4 hours. The reason lies in the physics of the materials: a thick layer of silicone creates a greenhouse effect. The skin inevitably begins to secrete sebum and sweat, the adhesive layer dissolves, and the heavy (that's the key word!) pad inexorably pulls the breasts down, distorting their natural proportions.
Moreover, under thin fabrics such as silk or viscose, the dense edge of the silicone cup always shows through, creating an unnatural relief.

Alternatives for the chest: next-generation stylistic patches and stickers
So what should you use? Ultra-thin silicone nipple covers with a matte finish. Good nipple covers, priced between €15 and €30, have paper-thin edges, making them virtually blend into your skin. Pay attention to the adhesive: look for medical-grade acrylic adhesive, which is moisture-resistant and reacts to body heat, enhancing the hold.

If a dress with side slits also includes a deep neckline or an open back, pasties won't be enough to create a beautiful shape. This is where taping comes in.

I've personally tested over 15 different brands of kinesiology tape and double-sided clothing tape. Here's the main rule: sports kinesio tape and stylistic boob tape These are different products. Sports tape is designed for micro-movement of muscles and is too elastic. Styling tapes (boob tape) have a lower stretchability, allowing them to act as a rigid frame, lifting the breasts by 2–4 centimeters without a single strap.
Taping patterns for dresses with open sides are based on the principle of vertical support:
- Anchor fixation: The strip is glued from the bottom of the chest strictly upwards, going to the collarbones (if the shoulders are covered) or forming a cup from the bottom up.
- Side Block: Avoid applying tape around the side openings. All tension should be directed toward the front or back, depending on the cut.
- Using Double-Sided Fashion Tape: This is a transparent tape that holds the fabric of the dress in place. to the skin This is crucial! If your dress has a waist cutout, tape the edges of the fabric directly to the ribs. This will ensure that the cutout doesn't shift or expose excess skin when you walk or turn.

But there's a fair limitation: tapes don't work well on busts of size E or larger, especially if the dress is too revealing and strapless. The laws of gravity are harder to circumvent than the laws of fashion.
The Bottom of a Dress: How to Hide Panties with Deep Cutouts
The most challenging area is when the side cutouts fall below the hipbone. Classic panties, even with the thinnest straps, will ruin the geometric shape of the outfit. We have three professional scenarios for this.
1. Strapless panties (panties without side straps).
These are small fabric elements that attach to the front and back with reusable gel adhesive, leaving the sides completely free. A great option for cocktail parties. Limitation: They cannot withstand aggressive dancing and high humidity.

2. Built-in bodysuit.
If you're shopping for a luxury dress, consider this sartorial trick. A sheer nude mesh bodysuit is sewn inside, stretching the dress but creating the illusion of bare skin beneath the cutouts.
3. The Secret of Hollywood Costume Designers (Commando).
As Karla Welch, one of Hollywood's most influential stylists, points out, the best way to wear dresses with extreme cutouts is to wear no underwear at all. But not literally! At the atelier, we take a cotton gusset and attach it with spot stitches. directly to the lining of the dress in the desired area. You get hygienic safety, complete comfort, and a perfectly clean silhouette.

Even the most expensive €50 tapes will peel off at the wrong moment if you don't follow the proper preparation protocol. The most common mistake that causes girls to cry at graduations and corporate events is applying too much moisturizing body lotion before going out.
According to dermatologists' recommendations for the use of medical adhesives (2023), the skin where the tapes or Fashion Tape will be applied should be completely dry and free of oil. My protocol for clients:
- Take a shower without using body oils.
- Wipe the areas where the tape will be applied (chest, ribs under the fabric tape) with a regular alcohol wipe. This will remove the microscopic layer of sebum.
- Let the skin dry for 30 seconds and only then apply the application.

Removing tapes is a separate ritual. Never rip them off like a Band-Aid! You're guaranteed to cause microtrauma to the epidermis. Soak the tape generously in a cleansing oil for makeup removal or baby oil, wait 10-15 minutes until the acrylic adhesive dissolves and the tape peels away from the skin.
MioLook Checklist: Putting Together a Capsule of "Invisible" Underwear
In the age of smart consumerism, your basic wardrobe isn't limited to a white shirt and jeans. You should have a capsule of "invisible" underwear. Here's what's in my professional kit and what I recommend every woman who appreciates interesting styles (the total cost of such a set rarely exceeds €60-80):
- A roll of professional boob tape (matching your skin tone).
- A pack of matte silicone pasties with a smooth edge.
- Dispenser with double-sided Fashion Tape (for fixing the edges of dresses).
- Flesh-colored thong panties with laser-cut edges (for dresses without deep cutouts on the hips).
- Alcohol wipes and a mini bottle of hydrophilic oil.
In the appendix MioLook I advise my clients to create a separate category in their digital wardrobe—"Special Base." When you upload a new complex dress to the app, the AI system will help you associate it with a specific type of invisible bra. So, when you're getting ready for an event, you can immediately see that that dress from Zara or COS requires pasties and double-sided tape, without wasting your time trying on regular bras.

True style isn't just what others see. It's how you feel. The right invisible frame gives you freedom: you can dance, hug friends, laugh, and not have to adjust the hems of your dress every minute. And this confidence is more flattering than any designer cut.
