-
Since I started using them, my cleavage looks amazing and natural. I feel so much more confident—and yeah, guys definitely notice.
-
They’re incredibly comfortable, weigh nothing, and don’t move, even when I’m dancing. I honestly forget I’m even wearing them.
-
I wore them to meet up with my ex and he couldn’t stop staring at my chest… by the end, he asked me to get back together. They work better than any push-up bra I’ve ever tried.

How it works?
How it works?
Unlike other inserts, Sllowy Boost™ is designed with smart-fit technology that combines an anatomical shape, ultra-soft medical-grade silicone, and double adhesion (to both skin and clothing) for real, long-lasting results.
Sllowy Boost™ gently molds to your chest and works with the natural pressure of fitted clothes to keep your bust lifted, centered, and beautifully shaped, no marks, no discomfort.
How to place it?
How to place it?
Sllowy Boost™ is super easy to use and gives incredible results, thanks to its shape that adapts to all breast types and enhances them naturally.
Just make sure to place it after putting on your top — it partially sticks to the fabric, which helps keep it in place and creates that perfect push-up effect.

How Do I Wash It?
How Do I Wash It?
Hand wash only—avoid machine washing or tumble drying.
Gently clean the adhesive using your fingertips, being careful to avoid your nails to prevent damage. Rinse thoroughly with warm water to remove any residue. Shake off excess water and lightly press the inserts to remove any remaining moisture. Let them air dry in a clean, dust-free area.
Once fully dry, reapply the protective films to keep the inserts free from dust and lint.

Why Are My Inserts Not Working?
Why Are My Inserts Not Working?
Many users find it takes a bit of practice to get the best results with their inserts.
The most common challenges come from wearing incompatible clothing or forgetting to scoop, which helps create a natural-looking cleavage.
It's important to note that our inserts are not a sticky bra and shouldn't be used as one.
Like traditional inserts, SLLOWY inserts require support from clothing and cannot stay in place on their own.
To achieve the best results, it's essential to wear compatible clothing—ideally tight, non-stretchy, and thick fabrics.
If the clothing is too stretchy or loose, it won’t provide the necessary support to press the inserts against your chest and enhance cleavage.
